Aaron B, Thanks Aaron! When I was writing the script I kept in mind all the things I hate about most exhaust reviews.... Did you notice I didn't rev the engine to redline while parked? (my biggest pet peeve :) I used a skateboard, GoPro, a large LED light and a skateboard to shoot under the car while it was on ramps. Over all, I am pleased with how the video turned out. Sometimes you have a "good" plan, but when you shoot it it looks bad. I wonder what the exhaust will look like at the second year mark?
Well in most exhaust videos you normally get: Revs or drive by on a new install, which is great, but doesn't give you the real exhaust sound in my opinion. I've owned exhausts on almost all my cars and notice after awhile you break the mufflers in and they open up a bit which does change the sound from initial install. What are you using for the outside the car audio and video? It's very clean and I really would like to get a set-up like that to do driving videos, if you don't mind sharing of course. I would love to hear the exhaust at the 2 year mark and see an under shot again, I wonder if repainting would help it through our harsh Canadian winters? I know next year I will have to polish my stainless pipes due to all the surface rust.
Hey Aaron B, I have no issue sharing my set up. I use a GoPro Hero 4 Black on a 11" magic arm from Amazon with a 4.5" suction cup. The GoPro has an OK mic for the lower frequencies and with it being tucked in behind the car, there is not much wind noise. I also spend a little time in post production cleaning up the audio. I will add a 2 Year review video to the production schedule for July 2018, just for you :)
Motorvate DIY I own a 2017 ZL1 with a car I built 25 years ago which is a 650 HP monster/ sleeper but I still have the heart of a 20 year old when I drive these cars.lol
I was at the track Sunday racing my twin turbo Infiniti Q50. I got some work done on her with more to come. Love seeing the faces of the young guys while they go down in defeat.
You. Are. Awesome. Please keep the videos coming. I drive a g37 imported to north Africa, no dealers and barely any decent mechanics/electricians. This encourages me to fix and maintain as much as I can on my own.
You. Are. Very. Kind! For the most part, the G37 is fairly easy to work on with an OK amount of room to do what needs to be done. Also, the engine is not complicated and reliable.
Came back after watching tons of G35 catback videos. This is by far the best sounding of all in my opinion. It's deeper with no scratchy/raspy noise all while still sounding like an import..hard to explain. But thanks for the great video and nice ride!
Hey Jack Lansdale, Thanks for your kind words! Other than the sound, the other thing I like about the Stillen cat back exhaust was the excellent fitment when I put it on. I have not had a bang or rattle in the 4 years it has been on the car. As silly as it sounds, I look forward to the spring/summer when I can have the windows open while going through the gears :)
Thank you so much for this video. I recently bought a2011 g37 convertible sport and it came with a terrible universal cat converter job and made the car miserable to drive. I was looking for something quiet, but that will sound good when you get it on. This is the answer. I added Berk HFC and the Stillen exhaust and it's perfect. No drone, quiet when cruising and idling, but will let people know you're there when WOT. No rasp either. Thank you again for this video!
1:19 As a 20 yo, I can say that I despise the typical obnoxious exhausts that young people usually put on their cars because they think loud = sound good. The way I see it, I want to hear the engine as I drive, I dont want everyone in the neighborhood to be woken up if I happen to start it at 4am. This exhaust system sounds perfect. My 17 year old coworker bought an E34 525i BMW and I was impressed. Until he slammed it 3 inches the next day and intentionally cut a hole in the exhaust pipe to make it louder. I have resented him and his car tastes ever since.
Thanks for your comment. I haven't watched that episode in a few years so I re-watched it today. I still stand by how I felt 5 years ago... It is a very good exhaust, as it doesn't annoy the cops or neighbours, makes a fantastic sound for the driver, and is about to enter its 8th salty road, Canadian winter without any issues. Exhaust preference/sound level a personal choice. However, many regions have passed laws to combat any aftermarket/loud/strait pipe exhausts... this exhaust sounds just a little louder than stock, and allows the wonderful VQ sound!
Not really. There is surface rust on the Y-pipe, which is the hottest part of the Stillen Exhaust, so that expected. In two months, it will be 7 years old, and been through 7 salty Canadian winters, so I am VERY happy with it and how well it is holding up. This summer, I will be doing a 7 year update episode and you will see for your self.
Hey Hugh Anderson, I am glad you found this channel. Working on your own car is fun and can save you money. BUT you need to be careful and make sure everything you do is done properly so you don't cause any issues. Anyways, thank you for subbing!
Thanks... I put on that exhaust in 2016 and even 5 years later, I still love it and open up my windows just to hear it a little better. I think you will be happy with it :)
Hey Frank I noticed that the car has a bit of a hop at initial acceleration which is typical of Gs and Zeds. I have not done the mods you have done (K&N, Stillen exhaust at least not yet). I have gone for mods which increase the effectiveness of the power that the car puts down. To eliminate the hop I decided to install solid rear aluminum bushings. I had a shop do it and it was a TERRIBLE job but the end result can not be argued with and the car really does not ride that much more stiffly. Anyway enjoy your car and our salty Canuck winters . My ride (370Z) stays in the garage all winter.
Thanks for sharing your experience on the aluminum bushings. It must be nice to store you 370z for the winter...I drive mine year round and Krown it (oil sprayed) every year. With good snow tires, the RWD G37 does quite well.
Hey Salvatore Anzalone, Thanks for your kind words and for subscribing! There are currently 10+ episodes on the production schedule, 3 are already shot, and the next one is in post production right now. :)
Hey man i love your video ,very informative ,very articulate keep up the good quality video man ,thanks for explaining very clear and professional ,long life i am subscribing
This exhaust sounds healthy and round . . just like a Tuba playing in and orchestra, not loud but . . it's there! As a professional Porsche Racing car constructor and Racing driver, I am very much inclined to think that it would perform magnificently on a dyno too . . . tell me if I'm wrong ;)
Hey Johnny Vichi, Wow... thanks! I hope you subbed... Over the winter I have planned out/scripted about 9 episodes and will start to shoot once it warms up :)
Motorvate DIY hell yeah i did. just reallllly on the fence between some acura tl 08, this g37 '10, tsx, avalon, accord, 328i e90, a4 b8 , etc etc, i can't make up my mind and i'm just going on a infinite rabbit hole on the tube to try and get one youtuber to push that final button for me lmfaooooooo
@@JohnnyVichi Thanks for subbing! From your list there are only 2 models that I would consider: G37 and the 328 E90. The smoothness of the 328 is wonderful due to the inline 6, but the power of the G37 is also nice. You will spend more on maintenance with the 328 than the G37. Go for a few test drives and see which one you like best :)
Can you do a video on replacing injectors??? Love the videos, you put in a lot of effort into your videos. I enjoy watching them. Any other upcoming mods planned?
Hey Lorentzoe 45, Maybe... but only if I need to replace them for a failure or upgrade. Thanks for the comment on the effort, I am glad you noticed. It is very interesting how much time it takes to make something short and to the point, without loosing too much detail. On average each episode takes about 50 hours of scripting, shooting, and editing. Many people have commented that I should get a "tune", but in Toronto the cost is around $1,000, which is more than I want to spend for the HP gains. Mod Options for 2018: - K&N vs New OEM vs no filter dyno take 2 - Post MAF Tubes with before/after dyno mght be in my future. - Street/Track brake pads. Even with the Sport Brakes, by OEM pads didn't do very well. A Future episode will provide details. - NAV update? not really a mod, but my area has changed a lot since 2011 :) - DIY Larger Power Steering cooler from junk yard parts. - DIY engine oil cooler from junk yard parts. - DIY oil pressure gauge., yup from junk yard parts. That is the plan for now, but it could all change in the spring!
Thank you for this video! It’s two years as of writing this and I found your series on the exhaust very helpful. On your installation video, you shared that your car gained 5 HP just on the install. Have you had it tuned since then, and if so do you recall seeing additional gains?
Hey Alec W, I have not had the car tuned just yet... I am going to be working with a tuner in California later this summer and do an e-tune. I would expect additional gains with a tune. Most G37/370z seem to get 10-15 HP with a tune.
That's a hard question to answer as I installed it just over 7 years ago, but I seem to remember a bit more pick up... as for MPGs, I don't know as I don't measure that. BUT, I can tell you with absolute certainty that I still LOVE the sound 7 years later! I'm glad the channel has helped you. We need to keep the last and best Infiniti running for a long time :)
Very nice review. I just bought a 2014 Pearl White Nissan Maxima, just turned 30,000 Miles. Been looking on UA-cam last few weeks listening to all the different exhaust systems, for the 2009-2014 Maxima's. Want something a little louder than Stock, Not Super Loud and Popping, like alot of the people doing Mufflers and Resonator Deletes, i think they sound like Shit especially Resonator Deletes. The Stillen looks like Excellent Quality and the Sound I'm looking for. Seems like you're Happy with your Stillen Exhaust. I will probably be ordering mine up soon. Just gotta decide on the Axle Back for around $500 or the Cat Back around $880. Just seems like alot of extra money if i go with the Cat Back, which includes the Resonator Pipe, for about $380 More than the Axle Back System.
Hey Bad Ass 6.0 Powerstroke, Thanks for your kind words! In my opinion, if you can afford the extra, I would get the cat back. It should give a little more performance than the stock y-pipe. If you just want a nice sound, axle back is a good choice for less money. Good luck!
@@MotorvateDIY Thanks, most likely be going with the Entire Stillen Cat Back, along with the Stillen Cold Air Intake. Seems like you're Happy with the Stillen ? Like i said I'm just looking for a Little more Sound than the Stock System. And the Quality looks Excellent.
Hey Bad Ass 6.0 Powerstroke, I have had the Stillen exhaust on my car for almost 4 years and I still roll down my window (on warm days!) just to hear the exhaust a little better. I hope you will enjoy it as much as I do. Also, the build quality is VERY good. Installation was easy and to this day it hasn't rattled or banged anything . Also, it doesn't hang down low and scrap over speed bumps. I know this sounds like it was "Sponsored by Stillen" but I am just a happy customer!
@@MotorvateDIY Thanks for your Review on the Stillen Cat Back Exhaust. I just ordered for my 2014 Nissan Maxima, Stillen Cat Back Exhaust, Stillen Cold Air Intake, And Stillen Rear Sway Bar. So far I'm Very pleased with the Customer Service, believe i spoke to Vice President of Company, asked if they can do me any type of Discount for ordering all 3 items, knocked almost $150 OFF My Total. Can't wait to receive and get on my Maxima. Excellent Review by the way, you really persuaded me to go with Stillen.
Great review man Thanks! I'm considering getting these for my G37 coupe. My question....is it looks like your muffler was sitting REALLY Low, maybe it was the angle but does it sit very low? Or scrape easily?
The factory muffler is slightly angled up at the back and the tips are oval to give more ground clearance. The Stillen exhaust mufflers are not angled up and has larger round tips. In the 5 years I have had the exhaust, it only scraped once exiting a driveway.
I had the Stillen exhaust for my awd xS sedan a few years back. The 7 speed auto with this exhaust drones a lot. It’s been 6 years since I’ve went back to stock but I have the Stillen in my garage. Been thinking about putting it back on if I can some how do something to minimize drone.
Motorvate DIY So I put my exhaust back on after it’s been in storage for over 6 years. I polished all the parts and had a different mechanic put it back on and this time zero drone. I think the last install must have been done wrong. This is quiet and aggressive at the same time. I’m in love with my car all over again. I also feel a slight power gain through the rpms based on but dyno. Strange since back the first time I felt like I lost low end torque.
Has any one had an issue with exhaust/or burnt fuel smell in the car with the windows down? The smell only comes in when I accelerate with windows down? I have a stock 2010 G37x coupe with 75k miles. The smell is pretty strong so it’s it’s concerning to me. I have mentioned this to Infiniti dealer and to local mechanic, but there has been no definitive answer. It’s driving me crazy.
Hey Lauren Stephens, That is funny! I honestly think as time goes on, the G37 will be a very car, like the older GT-Rs. The car does so many things just right... and with the option to have a 4 door sedan with a 6 speed manual is icing on the cake!
Excellent video! Question I was hoping you'd answer is, did you notice any performance difference at all between stock and Stillen catback? Sure, it sounds awesome, but I don't want to invest into it, just because it sounds nice.
Hey BlkHwkGator, Thanks for your kind words :) I did feel a difference, but I wonder my "feel" in influenced by the exhaust sound. Anywys, I did dyno the car before and after the Stillen cat back: Here is that episode: Stillen Cat Back Dyno: G37 Sport Sedan - Motorvate's DIY Garage Ep. 11 ua-cam.com/video/6tgCJaDX_S4/v-deo.html
No, not at all. However, in looking at Stillen's site the 07-08 exhausts are different than the 09-13 G37s. Maybe contact Stillen and see if there is a fix?
Love your videos! What kind of spoiler do you have on your G? Is it a Grubbs? Also: How was the car during winter? I got my G37s over spring and it's my first RWD car so with winter coming up kinda worries me haha. I'm glad I got it with winter tires at the very least.
Hey pat_0701, Thanks for the kind words on the videos. It's a labour of love! I don't know which spoiler you are talking about (front or rear) , but both are Infiniti accessories. My car is from California and I suspect that area had an unique package that included different rims (9 spoke), front and rear spoiler and the "midnight" (black) grill. As for winter driving, with your winter tires you will be fine. The traction/stability control work VERY well. You might want to find na empty area during a fresh snow fall, turn off stability/traction control and see what the car does. I find it to be very predictable and easy to "catch" when the rear steps out.
Funny you should mention that... I just watched a video of a modified 370z and it had that exact "trumpet" sound.... I put on my Stillen exhaust in 2016 and after 6 salty winters, it is still doing well... and to this day, I roll down the rear windows just to hear it a little better :)
Here is our episode comparing the stock exhaust to the Stillen cat back exhaust: Stock vs Stillen Cat-Back Exhaust Comparison: G37 Sedan - Motorvate's DIY Garage Ep. 4 ua-cam.com/video/egHsIvVV0QI/v-deo.html Also, the exhaust tips are 4" in diameter.
I have a stock 2013 coupe I enjoy. I drove it from Chicago to Toronto last summer and it did great! Bike fit in there well. So there is no drone around 2k rpms at 7o mph? my 7 speed auto sits there on the highway.
Hey Stonewall Jackson, With the 6 speed manual, I am just over 2,500 RPM at 70 MPH (113 KPH) and there is no drone to my ears. Keep in mind, the coupe exhaust is TOTALLY different than the sedan. The sedan has 2 mufflers and the coupe has one shared muffler and this may change the overall sound.
i have a 2007 g35 sedan and im looking at the stillen cat backs and they have gen 1-3, is this either of them? im looking for something loud but not muffler delete loud
This is the Stillen exhaust I have: stillen.com/collections/exhaust/products/2009-2013-infiniti-g37-sedan-2015-q40-stainless-steel-cat-back-exhaust-system-504377 This is the Stillen exhaust for your car: stillen.com/collections/exhaust/products/2007-2008-infiniti-g35-sedan-stainless-steel-cat-back-exhaust-system-504375 They don't look to be very different. I would expect them to sound about the same. If you are looking for something loud, I don't think you would be happy with the Stillen exhaust.
Hey man, another great vid as always! I was curious, are you running stock cats on the setup in this vid? I ask because I'm thinking about running stock 🐈 s for awhile as i upgrade my exhaust soon. I figure mine are still good and i dont want that hissing sound ive noticed quite a few Gs make when they lift off the throttle (with aggressive cats). Anyhow your G looks and sounds good, cheers man 🍺
This is a hard question to answer as you might hear things differently (aka better) than my 50+ year old ears. With that said, it is a "little" louder than stock, but not enough that you need to turn up the radio.
Hey Brian, I am a little confused.... Generally, "down pipes" are only used on turbo engines... The G37 is not a turbo engine... so I don't understand what you are asking. Are you thinking of "test pipes" that replace the cat?
Hey mate was just wondering would 650cc Injectors at least give you 50hp And would a race radiator increase hp? Love your videos exhaust sounds amazing!!
Hey Mustafa Jabakhanji, Thanks for your kind words! With out knowing the any details of intake/exhaust/engine mods, 650cc injectors are probably too big. Race rad -> no gain that I can see. The factory cooling system works well.
Hay Manjot, In looking at the Stillen.com site, the G35 sedan uses a different exhaust (part number: 504375) than the G37 sedan (part number 504377), so I don't think the G37 exhaust will fit your G35. :( But you could buy the Stillen exhaust for the G35 :)
Hey Brody Dover, My 3 answers for you: (1) Never (2) Never (3) Yes.... and I really like it :) Right now the car makes good power and don't feel the need to spend a few thousand dollars to make it a little quicker. One of my favorite quotes: "It is more fun to drive a slow car fast, than a fast car slow" BUT in the spring I will be upgrading the brakes and maybe tires/wheels / oil cooler and other items so it can handle a track day better. In an upcoming episode I will be showing what episode 22 - Handson's Advanced Driving School (ua-cam.com/video/iGbbYkfrGGY/v-deo.html) did to the stock pads. It was not good! BUT I am open to donations, with the promise to dyno before and after :)
Hey nandosman, Good question. Once per year, I get my car sprayed oil at Krown Rustpoofing (krown.com). They spray the underside and inside the doors, hood and trunk. They do have to drill some small holes to do this, but after they spray in the oil, they put in plastic plugs with great to prevent any corrosion. Also, I take my car through a car wash about every 3-4 weeks. They have an under body of water spray which should reduce the salt on the bottom of the car. Also, if possible, try not to drive the car when salt (or the sticky salt brine) is just being dumped on the road.
Hey Steven Martinez, Generally, catalytic converters are legally required for any street legal car. For off-road purposes, the catalytic converts can be replaced with a "test pipe" So, you can use a test pipe with this (or any other) exhaust. BUT since the engine control unit (ECU) is always testing how well the catalytic converter is working, you will get a check engine light with a P0420/P0430 code "Catalyst Converter efficiency below threshold" unless you get a custom ECU tune or use a rear o2 sensor extension tube.
So happy I came across your channel. Being I'm a little bit older and have a long drive to work I'm sold on the stillen exhaust. I was wondering what your thoughts might be on adding high flow cats? Too loud, maybe more drone?. Also what was the paint you used. I live in illinois and t Hi k that was a fantastic idea! Cheers to you man!
Hey Hunter & Ales Brewing, I am glad you found my channel :) My biggest worry with the high flow cats, is a check engine light for a "Catalyst System Efficiency Below Threshold" code. There have been a few folks on the G37 forums that have spent the money and labour getting the hi-flow cats installed, only to have a check engine light come after a while. If you don't have an emission test, then I guess that you don't need to worry. Where I live we have an emissions test every two years and I don't want to take a chance. PLUS I really don't want my car any louder. This is the paint that I used: www.por15.com/HIGH-TEMP_p_104.html P0420 Catalyst System Efficiency Below Threshold Read more at: www.obd-codes.com/p0420 Copyright OBD-Codes.com P0420 Catalyst System Efficiency Below Threshold Read more at: www.obd-codes.com/p0420 Copyright OBD-Codes.com P0420 Catalyst System Efficiency Below Threshold Read more at: www.obd-codes.com/p0420 Copyright OBD-Codes.com P0420 Catalyst System Efficiency Below Threshold Read more at: www.obd-codes.com/p0420 Copyright OBD-Codes.com P0420 Catalyst System Efficiency Below Threshold Read more at: www.obd-codes.com/p0420 Copyright OBD-Codes.com
Thanks for the quick response. I dont have emissions where I'm at (in the country) but I think just adding the extra diameter is going to be enough to help the V.Q unleash some noise. I appreciate your video and link to the paint and ODB 2 codes. Thanks a ton. Freaking love my G37. Every time I drive it I have a huge smile. Only issues I'm having are with my cluster. 😡 temp gauge and gas gauge LED's went out along with the analog clock. I might need to play with the clock to see if I wanna tackle the cluster. Only 70,000 miles on her right now. Cheers to you! I look forward to more videos!
Hey Hunter & Ales Brewing, We share the same thoughts on the G37.... big smile every time we drive it, especially with the windows down in the summer with the Stillen exhaust. I love it :) That's odd about your temp and gas gauge LEDs going out. Your gas and temperature gauge both have 4 surface mount LEDs to light the dial and the needle. Are the back of the temp/gas gauge out AND the needles?
Windows down sounds like a dream right now! Lol Both temp gauge and gas gauge needles are illuminated. The back lighting is out. During the day its difficult to read with the glare but I can see where the needle is. The temp gauge back lighting was going in and out at first but now completely off. I feel like the gas gauge is acting a little weird as well but I think I found out that reason. Going to put a couple bottles of Chevron Techron Plus in the tank within the next couple of fill ups. I've searched and searched and searched for anything related to the gauge lights but have come up empty. Only thing I can think is that they are out along with the analog Infiniti clock. I just find it very odd that it would have done that with only 70,000 miles on it. I've checked the fuss box down by the left foot and everything looked good. I thought about reaeting the ECU but I didnt want to go there just yet till I did more research.
It sounds like you have a few burned out LEDs in your gauge cluster. They are not easily changed (surface mount LEDs + gauge cluster must be 100% dismantled) , unlike the old days when you could replace a bulb. Your analog clock and gauge back light issue are not related. They are on two different circuits. The clock issue is not wide spread, but it is known. Do a quick search on my37.com to see how others have fixed this. There is no need to reset your ECU, it doesn't control your dash lights. The "Unified Meter and A/C Amp" does.
Hey Torvarris Brown, I don't know. The exhaust is different between the sedan and the coupe. However, on my sedan I have been very happy with the quality and the sound of the Stillen exhaust.
Hey Jay z, I do track my fuel economy and here are the results for 2017 so far: Stop and go traffic I average about 12.5 liter/100KM or almost 19 mpg. On the highway I average about 10 liter/100KM or just over 23 mpg.
@@MotorvateDIY Thanks for the quick reply. Some users say the K&N filters don’t fit perfect and that you have to force it to settle it in, and also that it is over-oiled. Is that true ? Also can you give me a link to that K&N filter ? Or part number ?
Hey Kevin Fuller, I purchased my exhaust at Whitehead Performance and they had it in about 2 weeks: whiteheadperformance.com/product/stillen-stainless-steel-cat-back-exhaust-system-504377-infiniti-g37-sedan-09-13/
Hey Francisco Mendez, I live in Canada and purchased it from a shop in Toronto called "Whitehead Motorsports" Here is a link to it: whiteheadperformance.com/product/stillen-stainless-steel-cat-back-exhaust-system-504377-infiniti-g37-sedan-09-13/ As the value of the Canadian dollar changes, so does the price of anything that comes from the US. When I purchased the exhaust in 2016 it was $1,626 and now it is $1,987 (from the above link)
Hey DailyActivity, Yes, that's the one :) www.stillen.com/catalog/product/view/id/92181/s/stillen-2009-2013-infiniti-g37-sedan-2015-q40-stainless-steel-cat-back-exhaust-system-504377/
Hey Marcus Aurelius, A used one would sound the same and cost much less. If you can find one, it would save you a lot of money... or you could spend the saving on something else for your car ].
Also.... thanks for subscribing! I am working on some very interesting future episodes right now. For example: What makes more power a K&N filter or NO AIR FILTER... That episode should be very interesting!
Hey Curtis Bledsoe, Sorry, but I don't know. The place I purchased my Stillen exhaust from orders a bunch of parts, then drives a truck to the US to pick them up. Anyone else know?
Curtis Bledsoe i just ordered the carbon fiber tip cat back for my 2018 Q60. From order to delivery I’m looking at 12 days (CA to FL). If it gets here on time this week that is 😬
Largely unrelated to what you stated in the video, but I just purchased this exhaust & upon inspection there is a decent amount of debris in the pipes (Looks like metal shavings & a black residue of some sort), the bar welded to the y pipe is crooked, & the internal pipe on the right before it splits has a dent. Bought it brand new & am a little dissapointed. Did you experience any of this by chance?
Do you drive a Q50? I saw a post talking about this, today. When I put this exhaust on in 2016 it was VERY well built and didn't have any of the issues you mentioned. I wonder if you ended up getting a counterfeit Stillen exhaust.
@@MotorvateDIY I drive a G37 Sedan, completely forgot to mention that; The exhaust says Stillen on the muffler outlets as it was pictured when I bought it from redline360 who state that they are an authorized Stillen dealer. However the weird welding job on the y pipe bar & internal dent isn't what I expected having watched this video before purchasing & reading many reviews. Perhaps it is a convincing counterfeit, or I just happened to get an authentic with some defects. Not ideal either way. I'll probably call Stillen to see if they can help.
Calling Stillen is a good idea. Maybe they have changed the exhaust design... All I can say is that the exhaust I received in 2016 was everything I had hoped for and was very well built. Maybe things are different in 2022... Let me know how you make out.
Are you still running the drop in K&N filters? I'm curious as to the combinations effect on your fuel economy. I feel like when I installed my stillen exhaust my economy dropped horribly and I thought that maybe I had a leak or I might just have a lead foot haha
Hey Omar Hossain, Yes, I still have the K&N drop in filters. As for a change in fuel economy with the Stillen exhaust I really can't say. My driving is not consistent enough for the data to mean any thing. For example, with the construction in my area, it often takes me an hour in stop and go traffic to do 32 km (20 miles). Then on the weekends, I can do the same 32 KM in under 20 minutes. In stop and go traffic I average about 12.5 liter/100KM or almost 19 mpg. On the highway I average about 10 liter/100KM or just over 23 mpg.
Motorvate DIY ok I just ask because I was averaging 22mpg before the install and now I'm at 19.7mpg. I can't really tell at the moment if it's the exhaust specifically because the cold weather has started in my area so that could be the reason why I'm experiencing the fuel economy dip. Thank you for your feedback I am a fan of your channel and watching your vids actually led me to purchasing the stillen catback! Thanks again!
Hey Omar Hossain, I hope you enjoy your Stillen Cat back as much as I do, which is daily! Thanks for your kind words on my channel. It has been a very positive experience for an old guy like me to jump into UA-cam.
Motorvate DIY old or young if the content is good I watch it haha! I'm putting new wheels, tires and sways on today, but keep making great videos..... they give me ideas on ways to improve my G without breaking my bank account lol

@@MotorvateDIY thanks for the reply good Sir! Sounds nice! I want to get his exhaust but with test pipes but I know it'll probably sound very raspy, even with resonators. Maybe I should go vibrant ultra quiet resonators
@@motobazuka2535 I think you are right about the sounds of the test pipes. It is my understanding that the resonated Fast Intentions test pipes sound good. You might want to do some searching at myg37.com as there is a lot of good information there. Good luck!
exactly how every exhaust review should be done. Thank you!
Aaron B,
Thanks Aaron! When I was writing the script I kept in mind all the things I hate about most exhaust reviews.... Did you notice I didn't rev the engine to redline while parked? (my biggest pet peeve :)
I used a skateboard, GoPro, a large LED light and a skateboard to shoot under the car while it was on ramps.
Over all, I am pleased with how the video turned out. Sometimes you have a "good" plan, but when you shoot it it looks bad.
I wonder what the exhaust will look like at the second year mark?
Well in most exhaust videos you normally get: Revs or drive by on a new install, which is great, but doesn't give you the real exhaust sound in my opinion. I've owned exhausts on almost all my cars and notice after awhile you break the mufflers in and they open up a bit which does change the sound from initial install.
What are you using for the outside the car audio and video? It's very clean and I really would like to get a set-up like that to do driving videos, if you don't mind sharing of course.
I would love to hear the exhaust at the 2 year mark and see an under shot again, I wonder if repainting would help it through our harsh Canadian winters? I know next year I will have to polish my stainless pipes due to all the surface rust.
Hey Aaron B,
I have no issue sharing my set up. I use a GoPro Hero 4 Black on a 11" magic arm from Amazon with a 4.5" suction cup.
The GoPro has an OK mic for the lower frequencies and with it being tucked in behind the car, there is not much wind noise.
I also spend a little time in post production cleaning up the audio.
I will add a 2 Year review video to the production schedule for July 2018, just for you :)
It amazes me that you do not need to be young to have the need for speed and I am not alone.
Hey CRAZY HORSEPOWER,
I like to look at it like this... WE are young, just on the inside!
Motorvate DIY I own a 2017 ZL1 with a car I built 25 years ago which is a 650 HP monster/ sleeper but I still have the heart of a 20 year old when I drive these cars.lol
I was at the track Sunday racing my twin turbo Infiniti Q50. I got some work done on her with more to come. Love seeing the faces of the young guys while they go down in defeat.
Yeah , some nerds in their people movers think if you're a car enthusiast it equates with immaturity . So ridiculous.
You. Are. Awesome.
Please keep the videos coming. I drive a g37 imported to north Africa, no dealers and barely any decent mechanics/electricians. This encourages me to fix and maintain as much as I can on my own.
You. Are. Very. Kind!
For the most part, the G37 is fairly easy to work on with an OK amount of room to do what needs to be done. Also, the engine is not complicated and reliable.
Came back after watching tons of G35 catback videos. This is by far the best sounding of all in my opinion. It's deeper with no scratchy/raspy noise all while still sounding like an import..hard to explain. But thanks for the great video and nice ride!
Hey Jack Lansdale,
Thanks for your kind words!
Other than the sound, the other thing I like about the Stillen cat back exhaust was the excellent fitment when I put it on. I have not had a bang or rattle in the 4 years it has been on the car.
As silly as it sounds, I look forward to the spring/summer when I can have the windows open while going through the gears :)
Thank you so much for this video. I recently bought a2011 g37 convertible sport and it came with a terrible universal cat converter job and made the car miserable to drive. I was looking for something quiet, but that will sound good when you get it on.
This is the answer. I added Berk HFC and the Stillen exhaust and it's perfect. No drone, quiet when cruising and idling, but will let people know you're there when WOT. No rasp either.
Thank you again for this video!
Glad it helped.
7 years later, I still love my Stillen cat back exhaust!
Great video, great sound . Really interesting, Well presented with the information one want for this subject. THank you
Hey Stefan Boeykens,
Thanks for your kind words! The making of this episode was a lot of fun.
Right to the point and no nonsense introduction. Thanks.
Glad you liked it
1:19 As a 20 yo, I can say that I despise the typical obnoxious exhausts that young people usually put on their cars because they think loud = sound good.
The way I see it, I want to hear the engine as I drive, I dont want everyone in the neighborhood to be woken up if I happen to start it at 4am. This exhaust system sounds perfect.
My 17 year old coworker bought an E34 525i BMW and I was impressed. Until he slammed it 3 inches the next day and intentionally cut a hole in the exhaust pipe to make it louder. I have resented him and his car tastes ever since.
Thanks for your comment. I haven't watched that episode in a few years so I re-watched it today.
I still stand by how I felt 5 years ago... It is a very good exhaust, as it doesn't annoy the cops or neighbours, makes a fantastic sound for the driver, and is about to enter its 8th salty road, Canadian winter without any issues.
Exhaust preference/sound level a personal choice. However, many regions have passed laws to combat any aftermarket/loud/strait pipe exhausts... this exhaust sounds just a little louder than stock, and allows the wonderful VQ sound!
Awesome video! Just broke my exhaust not too long ago and wanted to go back to the dual set up and this is the video that made me choose stillen.
Nice! I have had my Stillen exhaust on my G37 for 5 1/2 years and I still smile every time I start it. I think you made a good choice!
@@MotorvateDIY Any rust of concern so many years later?
Not really. There is surface rust on the Y-pipe, which is the hottest part of the Stillen Exhaust, so that expected.
In two months, it will be 7 years old, and been through 7 salty Canadian winters, so I am VERY happy with it and how well it is holding up.
This summer, I will be doing a 7 year update episode and you will see for your self.
I also love the black paint you did my exhaust rusted bad after about a year of use in Philadelphia.
Hey Philip Jacob,
Thanks... The mufflers are still black, but the y-pipe merge area is a little more rusted.
Yeah I’m glad I came across this channel. Great DIY and very well explained. I’m definitely gonna start doing more myself now. Def Subscribe 👌🏽
Hey Hugh Anderson,
I am glad you found this channel. Working on your own car is fun and can save you money. BUT you need to be careful and make sure everything you do is done properly so you don't cause any issues.
Anyways, thank you for subbing!
keep the vids coming, do some engine/suspension mods and tutorials
Hey Edumacation95,
That's the plan :)
Really good exhaust video. Definitely in my future to get.
Thanks... I put on that exhaust in 2016 and even 5 years later, I still love it and open up my windows just to hear it a little better.
I think you will be happy with it :)
Cool stuff man. I'm from Toronto too. You should do more stuff to your G. I just bought a 2010 g37xS auto sedan
Hey Haris Wadud,
I do plan on doing more... right now I am in the "saving up" phase :)
Hey Frank I noticed that the car has a bit of a hop at initial acceleration which is typical of Gs and Zeds. I have not done the mods you have done (K&N, Stillen exhaust at least not yet). I have gone for mods which increase the effectiveness of the power that the car puts down. To eliminate the hop I decided to install solid rear aluminum bushings. I had a shop do it and it was a TERRIBLE job but the end result can not be argued with and the car really does not ride that much more stiffly. Anyway enjoy your car and our salty Canuck winters . My ride (370Z) stays in the garage all winter.
Thanks for sharing your experience on the aluminum bushings.
It must be nice to store you 370z for the winter...I drive mine year round and Krown it (oil sprayed) every year. With good snow tires, the RWD G37 does quite well.
Love your videos, keep em coming! You earned yourself a new subscriber 🇨🇦
Hey Salvatore Anzalone,
Thanks for your kind words and for subscribing!
There are currently 10+ episodes on the production schedule, 3 are already shot, and the next one is in post production right now. :)
Thanks for the great content. A fan from down under. I have a JDM V 36 Skyline 370GT.
You are welcome. Once things get back to normal, I need to make my way to Australia, it looks like horsepower heaven :)
Hey man i love your video ,very informative ,very articulate keep up the good quality video man ,thanks for explaining very clear and professional ,long life i am subscribing
Hey Miguel Vasquez,
Thanks for your kind words, you have made my day :)
Also, thanks for subbing!!
@@MotorvateDIY my pleasure ,thanks for your great videos
I know this video is old but they sell hight temp spray that's rated for 2000 degrees at the auto parts stores.
Looking back, that would of been nice to try. The Por 15 I used is rated to 1200F, which isn't high enough :(
This exhaust sounds healthy and round . . just like a Tuba playing in and orchestra, not loud but . . it's there! As a professional Porsche Racing car constructor and Racing driver, I am very much inclined to think that it would perform magnificently on a dyno too . . . tell me if I'm wrong ;)
Hey 911logic,
Nope, you are not wrong...
Here are my dyno results: ua-cam.com/video/6tgCJaDX_S4/v-deo.html
Love your vids!
Hey Jaden Jeong,
Thank you! I am working on the next episode right now...
Can't wait to get this !
To be honest, I still love my Stillen exhaust after almost 5 years... I hope you love yours as well :)
love all the vids ! by chance a sparks plug replacement vid soon ?
Hey Spade Moreno,
Yes! I am a little overdue on spark plugs. I plan on shooting the episode in a few weeks.
just found your video. man you rock
Hey Johnny Vichi,
Wow... thanks!
I hope you subbed... Over the winter I have planned out/scripted about 9 episodes and will start to shoot once it warms up :)
Motorvate DIY hell yeah i did. just reallllly on the fence between some acura tl 08, this g37 '10, tsx, avalon, accord, 328i e90, a4 b8 , etc etc, i can't make up my mind and i'm just going on a infinite rabbit hole on the tube to try and get one youtuber to push that final button for me lmfaooooooo
@@JohnnyVichi Thanks for subbing!
From your list there are only 2 models that I would consider: G37 and the 328 E90.
The smoothness of the 328 is wonderful due to the inline 6, but the power of the G37 is also nice.
You will spend more on maintenance with the 328 than the G37.
Go for a few test drives and see which one you like best :)
Can you do a video on replacing injectors??? Love the videos, you put in a lot of effort into your videos. I enjoy watching them. Any other upcoming mods planned?
Hey Lorentzoe 45,
Maybe... but only if I need to replace them for a failure or upgrade.
Thanks for the comment on the effort, I am glad you noticed. It is very interesting how much time it takes to make something short and to the point, without loosing too much detail. On average each episode takes about 50 hours of scripting, shooting, and editing.
Many people have commented that I should get a "tune", but in Toronto the cost is around $1,000, which is more than I want to spend for the HP gains.
Mod Options for 2018:
- K&N vs New OEM vs no filter dyno take 2
- Post MAF Tubes with before/after dyno mght be in my future.
- Street/Track brake pads. Even with the Sport Brakes, by OEM pads didn't do very well. A Future episode will provide details.
- NAV update? not really a mod, but my area has changed a lot since 2011 :)
- DIY Larger Power Steering cooler from junk yard parts.
- DIY engine oil cooler from junk yard parts.
- DIY oil pressure gauge., yup from junk yard parts.
That is the plan for now, but it could all change in the spring!
Thank you for this video! It’s two years as of writing this and I found your series on the exhaust very helpful.
On your installation video, you shared that your car gained 5 HP just on the install. Have you had it tuned since then, and if so do you recall seeing additional gains?
Hey Alec W,
I have not had the car tuned just yet... I am going to be working with a tuner in California later this summer and do an e-tune.
I would expect additional gains with a tune. Most G37/370z seem to get 10-15 HP with a tune.
You should look into getting an ecutek tune for your car. I’d love to see a video about it from you!
Hey Milan Parekh,
I think ECUTek has a great product, but the cost in Canada is over $1,000 and for me, that is too much money for too small a gain.
Notice any performance improvements? Better mpg? Love this channel has helped me a bunch
That's a hard question to answer as I installed it just over 7 years ago, but I seem to remember a bit more pick up... as for MPGs, I don't know as I don't measure that.
BUT, I can tell you with absolute certainty that I still LOVE the sound 7 years later!
I'm glad the channel has helped you.
We need to keep the last and best Infiniti running for a long time :)
Very nice review. I just bought a 2014 Pearl White Nissan Maxima, just turned 30,000 Miles. Been looking on UA-cam last few weeks listening to all the different exhaust systems, for the 2009-2014 Maxima's. Want something a little louder than Stock, Not Super Loud and Popping, like alot of the people doing Mufflers and Resonator Deletes, i think they sound like Shit especially Resonator Deletes. The Stillen looks like Excellent Quality and the Sound I'm looking for. Seems like you're Happy with your Stillen Exhaust. I will probably be ordering mine up soon. Just gotta decide on the Axle Back for around $500 or the Cat Back around $880. Just seems like alot of extra money if i go with the Cat Back, which includes the Resonator Pipe, for about $380 More than the Axle Back System.
Hey Bad Ass 6.0 Powerstroke,
Thanks for your kind words!
In my opinion, if you can afford the extra, I would get the cat back. It should give a little more performance than the stock y-pipe.
If you just want a nice sound, axle back is a good choice for less money. Good luck!
@@MotorvateDIY Thanks, most likely be going with the Entire Stillen Cat Back, along with the Stillen Cold Air Intake. Seems like you're Happy with the Stillen ?
Like i said I'm just looking for a Little more Sound than the Stock System. And the Quality looks Excellent.
Hey Bad Ass 6.0 Powerstroke,
I have had the Stillen exhaust on my car for almost 4 years and I still roll down my window (on warm days!) just to hear the exhaust a little better. I hope you will enjoy it as much as I do.
Also, the build quality is VERY good. Installation was easy and to this day it hasn't rattled or banged anything . Also, it doesn't hang down low and scrap over speed bumps.
I know this sounds like it was "Sponsored by Stillen" but I am just a happy customer!
@@MotorvateDIY Very Good, that's good to know. Thank You.
@@MotorvateDIY Thanks for your Review on the Stillen Cat Back Exhaust. I just ordered for my 2014 Nissan Maxima, Stillen Cat Back Exhaust, Stillen Cold Air Intake, And Stillen Rear Sway Bar. So far I'm Very pleased with the Customer Service, believe i spoke to Vice President of Company, asked if they can do me any type of Discount for ordering all 3 items, knocked almost $150 OFF My Total. Can't wait to receive and get on my Maxima. Excellent Review by the way, you really persuaded me to go with Stillen.
Great review man Thanks! I'm considering getting these for my G37 coupe. My question....is it looks like your muffler was sitting REALLY Low, maybe it was the angle but does it sit very low? Or scrape easily?
The factory muffler is slightly angled up at the back and the tips are oval to give more ground clearance.
The Stillen exhaust mufflers are not angled up and has larger round tips. In the 5 years I have had the exhaust, it only scraped once exiting a driveway.
I had the Stillen exhaust for my awd xS sedan a few years back. The 7 speed auto with this exhaust drones a lot. It’s been 6 years since I’ve went back to stock but I have the Stillen in my garage. Been thinking about putting it back on if I can some how do something to minimize drone.
Hey Philip Jacob,
That's odd, I don't have any drone with my G37 sedan 6 speed manual.
Good luck in reducing your drone.
Motorvate DIY So I put my exhaust back on after it’s been in storage for over 6 years. I polished all the parts and had a different mechanic put it back on and this time zero drone. I think the last install must have been done wrong. This is quiet and aggressive at the same time. I’m in love with my car all over again. I also feel a slight power gain through the rpms based on but dyno. Strange since back the first time I felt like I lost low end torque.
@@philipjacob2314 What's a drone ?
fantastic review. definitely love how it sounds. did you buy straight from stillen or is there a place with better deals
I am in Canada and it was cheaper to get it from Whitehead Performance in Toronto, than directly from Stillen, due to shipping costs.
Has any one had an issue with exhaust/or burnt fuel smell in the car with the windows down? The smell only comes in when I accelerate with windows down? I have a stock 2010 G37x coupe with 75k miles. The smell is pretty strong so it’s it’s concerning to me. I have mentioned this to Infiniti dealer and to local mechanic, but there has been no definitive answer. It’s driving me crazy.
Hey Bob Owen,
There shouldn't be any noticeable smell from your exhaust.
From your description, I would first look at the catalytic converters.
lol had i known a g37 sedan could sound like that, id have not JUST traded mine in!
Hey Lauren Stephens,
That is funny!
I honestly think as time goes on, the G37 will be a very car, like the older GT-Rs. The car does so many things just right... and with the option to have a 4 door sedan with a 6 speed manual is icing on the cake!
Excellent video! Question I was hoping you'd answer is, did you notice any performance difference at all between stock and Stillen catback? Sure, it sounds awesome, but I don't want to invest into it, just because it sounds nice.
Hey BlkHwkGator,
Thanks for your kind words :)
I did feel a difference, but I wonder my "feel" in influenced by the exhaust sound.
Anywys, I did dyno the car before and after the Stillen cat back:
Here is that episode:
Stillen Cat Back Dyno: G37 Sport Sedan - Motorvate's DIY Garage Ep. 11
ua-cam.com/video/6tgCJaDX_S4/v-deo.html
so i picked one up on my 2007 g35 sedan and i gotta say its got an incredible amount of drone at 2/3k rpms, did you have an issue with this?
No, not at all. However, in looking at Stillen's site the 07-08 exhausts are different than the 09-13 G37s.
Maybe contact Stillen and see if there is a fix?
Love your videos! What kind of spoiler do you have on your G? Is it a Grubbs?
Also: How was the car during winter? I got my G37s over spring and it's my first RWD car so with winter coming up kinda worries me haha. I'm glad I got it with winter tires at the very least.
Hey pat_0701,
Thanks for the kind words on the videos. It's a labour of love!
I don't know which spoiler you are talking about (front or rear) , but both are Infiniti accessories.
My car is from California and I suspect that area had an unique package that included different rims (9 spoke), front and rear spoiler and the "midnight" (black) grill.
As for winter driving, with your winter tires you will be fine. The traction/stability control work VERY well.
You might want to find na empty area during a fresh snow fall, turn off stability/traction control and see what the car does. I find it to be very predictable and easy to "catch" when the rear steps out.
Definitely going stillen. I can’t stand the raspy trumpet vq sound
Funny you should mention that... I just watched a video of a modified 370z and it had that exact "trumpet" sound....
I put on my Stillen exhaust in 2016 and after 6 salty winters, it is still doing well... and to this day, I roll down the rear windows just to hear it a little better :)
What would you think of ark? Vs what you have sir
I don't have any first hand experience with the Ark exhaust, so I can't answer your question. :(
What's the diameter on the exhaust piping? And show big are the tips?
Here is our episode comparing the stock exhaust to the Stillen cat back exhaust:
Stock vs Stillen Cat-Back Exhaust Comparison: G37 Sedan - Motorvate's DIY Garage Ep. 4
ua-cam.com/video/egHsIvVV0QI/v-deo.html
Also, the exhaust tips are 4" in diameter.
I have a stock 2013 coupe I enjoy. I drove it from Chicago to Toronto last summer and it did great! Bike fit in there well. So there is no drone around 2k rpms at 7o mph? my 7 speed auto sits there on the highway.
Hey Stonewall Jackson,
With the 6 speed manual, I am just over 2,500 RPM at 70 MPH (113 KPH) and there is no drone to my ears.
Keep in mind, the coupe exhaust is TOTALLY different than the sedan. The sedan has 2 mufflers and the coupe has one shared muffler and this may change the overall sound.
i have a 2007 g35 sedan and im looking at the stillen cat backs and they have gen 1-3, is this either of them? im looking for something loud but not muffler delete loud
This is the Stillen exhaust I have: stillen.com/collections/exhaust/products/2009-2013-infiniti-g37-sedan-2015-q40-stainless-steel-cat-back-exhaust-system-504377
This is the Stillen exhaust for your car: stillen.com/collections/exhaust/products/2007-2008-infiniti-g35-sedan-stainless-steel-cat-back-exhaust-system-504375
They don't look to be very different. I would expect them to sound about the same.
If you are looking for something loud, I don't think you would be happy with the Stillen exhaust.
Hey man, another great vid as always! I was curious, are you running stock cats on the setup in this vid? I ask because I'm thinking about running stock 🐈 s for awhile as i upgrade my exhaust soon.
I figure mine are still good and i dont want that hissing sound ive noticed quite a few Gs make when they lift off the throttle (with aggressive cats). Anyhow your G looks and sounds good, cheers man 🍺
Hey DevilG,
Thanks for your kinds words!
Yes, I am still running with the stock cats.
Perfect, you just sold me on this setup. Thanks for the reply and info
How much louder is it in the cabin compared to stock. Stock is quite loud inside the cabin.
This is a hard question to answer as you might hear things differently (aka better) than my 50+ year old ears.
With that said, it is a "little" louder than stock, but not enough that you need to turn up the radio.
@@MotorvateDIY does it come resonated or is that extra to muffle it some?
In your opinion, do you think that AMS downpipes would take it over the top from a loudness perspective?
Hey Brian,
I am a little confused.... Generally, "down pipes" are only used on turbo engines... The G37 is not a turbo engine... so I don't understand what you are asking.
Are you thinking of "test pipes" that replace the cat?
I would assume the sound is virtually the same for a 370z?
Nope... They have a VERY different exhaust system.
Hey mate was just wondering would 650cc Injectors at least give you 50hp
And would a race radiator increase hp?
Love your videos exhaust sounds amazing!!
Hey Mustafa Jabakhanji,
Thanks for your kind words!
With out knowing the any details of intake/exhaust/engine mods, 650cc injectors are probably too big.
Race rad -> no gain that I can see. The factory cooling system works well.
Question, i own a 07 G35S sedan. Want to know if a Stillen G37 sedan exhaust will fit my car? Any additional parts needed?
Hay Manjot,
In looking at the Stillen.com site, the G35 sedan uses a different exhaust (part number: 504375) than the G37 sedan (part number 504377), so I don't think the G37 exhaust will fit your G35. :(
But you could buy the Stillen exhaust for the G35 :)
Where did you buy parts?
I purchased the parts in 2016 from Whitehead Performance, however they closed in 2019 :(
My 3 questions: when are you getting an intake?
When are you getting a tune?
Does your G have the studio on wheels Bose?
Hey Brody Dover,
My 3 answers for you:
(1) Never
(2) Never
(3) Yes.... and I really like it :)
Right now the car makes good power and don't feel the need to spend a few thousand dollars to make it a little quicker.
One of my favorite quotes: "It is more fun to drive a slow car fast, than a fast car slow"
BUT in the spring I will be upgrading the brakes and maybe tires/wheels / oil cooler and other items so it can handle a track day better.
In an upcoming episode I will be showing what episode 22 - Handson's Advanced Driving School (ua-cam.com/video/iGbbYkfrGGY/v-deo.html) did to the stock pads. It was not good!
BUT I am open to donations, with the promise to dyno before and after :)
Great vids! Does it drone on an incline- under load?
Hey 101ThekMan,
Not to my ears, but it does humm a little louder under those conditions.
Do you have any additional tips to help with the winter/salt on the car overall?
Hey nandosman,
Good question.
Once per year, I get my car sprayed oil at Krown Rustpoofing (krown.com). They spray the underside and inside the doors, hood and trunk. They do have to drill some small holes to do this, but after they spray in the oil, they put in plastic plugs with great to prevent any corrosion.
Also, I take my car through a car wash about every 3-4 weeks. They have an under body of water spray which should reduce the salt on the bottom of the car.
Also, if possible, try not to drive the car when salt (or the sticky salt brine) is just being dumped on the road.
One question here, do you need catalytic converters with this exhaust ?
Hey Steven Martinez,
Generally, catalytic converters are legally required for any street legal car.
For off-road purposes, the catalytic converts can be replaced with a "test pipe"
So, you can use a test pipe with this (or any other) exhaust.
BUT since the engine control unit (ECU) is always testing how well the catalytic converter is working,
you will get a check engine light with a P0420/P0430 code "Catalyst Converter efficiency below threshold"
unless you get a custom ECU tune or use a rear o2 sensor extension tube.
So happy I came across your channel. Being I'm a little bit older and have a long drive to work I'm sold on the stillen exhaust. I was wondering what your thoughts might be on adding high flow cats? Too loud, maybe more drone?. Also what was the paint you used. I live in illinois and t Hi k that was a fantastic idea! Cheers to you man!
Hey Hunter & Ales Brewing,
I am glad you found my channel :)
My biggest worry with the high flow cats, is a check engine light for a "Catalyst System Efficiency Below Threshold" code.
There have been a few folks on the G37 forums that have spent the money and labour getting the hi-flow cats installed, only to have a check engine light come after a while. If you don't have an emission test, then I guess that you don't need to worry.
Where I live we have an emissions test every two years and I don't want to take a chance.
PLUS I really don't want my car any louder.
This is the paint that I used: www.por15.com/HIGH-TEMP_p_104.html

Thanks for the quick response. I dont have emissions where I'm at (in the country) but I think just adding the extra diameter is going to be enough to help the V.Q unleash some noise. I appreciate your video and link to the paint and ODB 2 codes. Thanks a ton. Freaking love my G37. Every time I drive it I have a huge smile. Only issues I'm having are with my cluster. 😡 temp gauge and gas gauge LED's went out along with the analog clock. I might need to play with the clock to see if I wanna tackle the cluster. Only 70,000 miles on her right now. Cheers to you! I look forward to more videos!
Hey Hunter & Ales Brewing,
We share the same thoughts on the G37.... big smile every time we drive it, especially with the windows down in the summer with the Stillen exhaust. I love it :)
That's odd about your temp and gas gauge LEDs going out. Your gas and temperature gauge both have 4 surface mount LEDs to light the dial and the needle. Are the back of the temp/gas gauge out AND the needles?
Windows down sounds like a dream right now! Lol
Both temp gauge and gas gauge needles are illuminated. The back lighting is out. During the day its difficult to read with the glare but I can see where the needle is. The temp gauge back lighting was going in and out at first but now completely off. I feel like the gas gauge is acting a little weird as well but I think I found out that reason. Going to put a couple bottles of Chevron Techron Plus in the tank within the next couple of fill ups. I've searched and searched and searched for anything related to the gauge lights but have come up empty. Only thing I can think is that they are out along with the analog Infiniti clock. I just find it very odd that it would have done that with only 70,000 miles on it. I've checked the fuss box down by the left foot and everything looked good. I thought about reaeting the ECU but I didnt want to go there just yet till I did more research.
It sounds like you have a few burned out LEDs in your gauge cluster. They are not easily changed (surface mount LEDs + gauge cluster must be 100% dismantled) , unlike the old days when you could replace a bulb.
Your analog clock and gauge back light issue are not related. They are on two different circuits. The clock issue is not wide spread, but it is known. Do a quick search on my37.com to see how others have fixed this.
There is no need to reset your ECU, it doesn't control your dash lights. The "Unified Meter and A/C Amp" does.
what this exhaust be gud for a g37s coupe
Hey Torvarris Brown,
I don't know. The exhaust is different between the sedan and the coupe.
However, on my sedan I have been very happy with the quality and the sound of the Stillen exhaust.
Do you know how much mpg usually in city/highway?
Hey Jay z,
I do track my fuel economy and here are the results for 2017 so far:
Stop and go traffic I average about 12.5 liter/100KM or almost 19 mpg.
On the highway I average about 10 liter/100KM or just over 23 mpg.
Can we know the mods that we in your G a the time of shooting this video ?
Sure... K&N panel air filter and Stillen cat back :)
@@MotorvateDIY Thanks for the quick reply. Some users say the K&N filters don’t fit perfect and that you have to force it to settle it in, and also that it is over-oiled. Is that true ?
Also can you give me a link to that K&N filter ? Or part number ?
I'm curious to know which dealer sells this exhaust in Ontario.
Hey Kevin Fuller,
I purchased my exhaust at Whitehead Performance and they had it in about 2 weeks:
whiteheadperformance.com/product/stillen-stainless-steel-cat-back-exhaust-system-504377-infiniti-g37-sedan-09-13/
Motorvate DIY thank you. I will definitely be giving them a call should this snow ever decide to go away.
How much was it and where did you ge it?
Hey Francisco Mendez,
I live in Canada and purchased it from a shop in Toronto called "Whitehead Motorsports"
Here is a link to it: whiteheadperformance.com/product/stillen-stainless-steel-cat-back-exhaust-system-504377-infiniti-g37-sedan-09-13/
As the value of the Canadian dollar changes, so does the price of anything that comes from the US.
When I purchased the exhaust in 2016 it was $1,626 and now it is $1,987 (from the above link)
is this part #504377 stillen kit?
Hey DailyActivity,
Yes, that's the one :)

New subscriber here! Would it be a bad idea to buy a used one? I don't feel the need to pay 1200 for a new one if I'll only use it in the summers.
Hey Marcus Aurelius,
A used one would sound the same and cost much less. If you can find one, it would save you a lot of money... or you could spend the saving on something else for your car ].
Also.... thanks for subscribing! I am working on some very interesting future episodes right now. For example: What makes more power a K&N filter or NO AIR FILTER... That episode should be very interesting!
Motorvate DIY looking forward to it thanks! Next up is an aftermarket intake for my G35s sedan 6mt!
Dose anyone know how stillen takes to ship out parts
Hey Curtis Bledsoe,
Sorry, but I don't know.
The place I purchased my Stillen exhaust from orders a bunch of parts, then drives a truck to the US to pick them up.
Anyone else know?
Curtis Bledsoe i just ordered the carbon fiber tip cat back for my 2018 Q60. From order to delivery I’m looking at 12 days (CA to FL). If it gets here on time this week that is 😬
Largely unrelated to what you stated in the video, but I just purchased this exhaust & upon inspection there is a decent amount of debris in the pipes (Looks like metal shavings & a black residue of some sort), the bar welded to the y pipe is crooked, & the internal pipe on the right before it splits has a dent. Bought it brand new & am a little dissapointed. Did you experience any of this by chance?
Do you drive a Q50? I saw a post talking about this, today.
When I put this exhaust on in 2016 it was VERY well built and didn't have any of the issues you mentioned.
I wonder if you ended up getting a counterfeit Stillen exhaust.
@@MotorvateDIY I drive a G37 Sedan, completely forgot to mention that; The exhaust says Stillen on the muffler outlets as it was pictured when I bought it from redline360 who state that they are an authorized Stillen dealer. However the weird welding job on the y pipe bar & internal dent isn't what I expected having watched this video before purchasing & reading many reviews. Perhaps it is a convincing counterfeit, or I just happened to get an authentic with some defects. Not ideal either way. I'll probably call Stillen to see if they can help.
Calling Stillen is a good idea. Maybe they have changed the exhaust design... All I can say is that the exhaust I received in 2016 was everything I had hoped for and was very well built.
Maybe things are different in 2022... Let me know how you make out.
@@MotorvateDIY I will do that, thanks for the help
I agree with what SonicVQ said... "Don't sweat it. Just enjoy the sound of your new exhaust"
I know I do when passing through any/every tunnel :)
Are you still running the drop in K&N filters? I'm curious as to the combinations effect on your fuel economy. I feel like when I installed my stillen exhaust my economy dropped horribly and I thought that maybe I had a leak or I might just have a lead foot haha
Hey Omar Hossain,
Yes, I still have the K&N drop in filters.
As for a change in fuel economy with the Stillen exhaust I really can't say. My driving is not consistent enough for the data to mean any thing. For example, with the construction in my area, it often takes me an hour in stop and go traffic to do 32 km (20 miles). Then on the weekends, I can do the same 32 KM in under 20 minutes.
In stop and go traffic I average about 12.5 liter/100KM or almost 19 mpg.
On the highway I average about 10 liter/100KM or just over 23 mpg.
Motorvate DIY ok I just ask because I was averaging 22mpg before the install and now I'm at 19.7mpg. I can't really tell at the moment if it's the exhaust specifically because the cold weather has started in my area so that could be the reason why I'm experiencing the fuel economy dip. Thank you for your feedback I am a fan of your channel and watching your vids actually led me to purchasing the stillen catback! Thanks again!
Hey Omar Hossain,
I hope you enjoy your Stillen Cat back as much as I do, which is daily!
Thanks for your kind words on my channel. It has been a very positive experience for an old guy like me to jump into UA-cam.
Motorvate DIY old or young if the content is good I watch it haha! I'm putting new wheels, tires and sways on today, but keep making great videos..... they give me ideas on ways to improve my G without breaking my bank account lol
Hey Omar Hossain,
Have fun with your wheels, tires and sway bars as I am sure you will :)
I will try to save you some more money with December's episode "How to properly clean your throttle body" which goes into post production in 2 weeks.
Is it loud?
Not in my opinion... I think it is a nice growl.
Is the awd or rwd?
Hey Zachary Price,
This car is rear wheel drive.
Stillen says this exhaust will fit AWD as well:
stillen.com/collections/exhaust/products/sti504377
Title should include what car you're talking about.
Hey ptatohed,
Thanks for the tip... I have added it to the title and description.
Hey ptatohed,
Sorry for the late reply! It is a 2011 Infiniti G37
This is with stock cats?
Hey moto bazuka,
Yes. Stock cats with Stillen cat back exhaust and K&N drop in panel filters. Stock tune.
@@MotorvateDIY thanks for the reply good Sir! Sounds nice! I want to get his exhaust but with test pipes but I know it'll probably sound very raspy, even with resonators. Maybe I should go vibrant ultra quiet resonators
@@motobazuka2535 I think you are right about the sounds of the test pipes. It is my understanding that the resonated Fast Intentions test pipes sound good. You might want to do some searching at myg37.com as there is a lot of good information there.
Good luck!
04:07 OMG... the horror.
Hey JB Hix,
It took me a while to understand your comment, but I finally got it :)
Driving the G37 in the snow is a lot of fun!
I live in Nevada, which ironically means “snow” in Spanish. Not a lot of snow though. Mostly desert.
