@@stevehuk902 it’s not something easily captured on camera, because the valve is open below 20mph or above 4,500 rpm anyways. It’s the midrange that you pick up sound, which is touch to capture.

Fair enough

nope, its a a gimmick. The turbo / catalytic convertor is the biggest restriction in the exhaust

@mpgcamo I would like to see dyno numbers. It’s not a question of restriction, if the exhaust causes loss of back pressure at lower RPM it can impact your torque at those levels. Definitely at high RPM you want as much free flow as possible that’s why Toyota engineered the center exhaust to open at over 4k rpm. I wouldn’t call it a gimmick

@ in an NA motor back pressure or scavenging is important. On turbo engines when the turbo is being fed by very short runners from the engine, back pressure means nothing the only thing you need to worry about on a turbo motor is flow. It’s as simple at that. This is why turbo motors aren’t built with equal length primaries on manifolds and often just have a collector or log style manifolds.

@mpgcamo until boost kicks in at 4-5k this engine is relying on atmospheric pressure. Furthermore isn’t it interesting that Toyota chief engineer states the reason they added the center exhaust was to reduce back pressure at high RPM, that was one of the ways they were able to extract more power. As one adds bolt on components and tune the engine the first hurdle you hit is valve float. The valve float is induced when our friend, back pressure, pops its head up again as engine output crosses a particular threshold. What you stated in your comment sounds valid but with larger displacement turbo engines since there is much more volumetric headroom with a bigger engine

@@Goo475 that’s probably not what I would do, simply because those are two different substrates. For asphalt, you can buy a melt-in filler. Apply using a caulk gun then hit it with a torch. Then use a top coat of your choosing and it should be good as new!

I have seen it done that way, and by all means that’s a solid repair. I considered that first, but wanted to try this method because when I did this repair a year ago, dry pour was a new process that a lot of people were experimenting with. I gave it a shot and it’s still holding up a year later.

And what’s funny is even with the disclaimer, people still comment on how I’m doing it wrong. Lmao. It’s holding up really well. Actually still looks just like the day I made the video. It was a cheap, effective shortish term solution. I recommend.

Actually, the way you see it in the video is exactly how it looks today. Was it the proper repair? No. I know that. Was it cheap, easy and drastically improve how it looks? YES! It served the purpose I set out to accomplish.

@@X_theOracle they look like little pucks, just behind the front tires and just in front of the rear tires.

@@Jovi__ Are they rubber?

@@X_theOracle yeah I believe so. It’s been awhile since I’ve lifted it.

Nice! I love it!

@@Jovi__ does your GR feel like its a little more slugish? after driving mine and getting on it it feels slugish compared to the oem intake.

@@GRRiizzyJ at first I did kinda think that, but the more I drove it, the more it seemed to come into it. My thoughts are the car saw the change and had to adjust for it. Just drive it some more and see what it does.

@@Jovi__ I was thinking that too bro thank you didn’t wanna think I did something wrong 😂

@@GRRiizzyJ no problem man. Just realize you introduced a lot more cooler air coming in, and the car isn’t quite sure what to do with that until it learns how it should be. It’s crazy how advanced cars are now. It’ll pull timing or advance timing as it sees fit, and when we introduce a variable it’s not familiar with it will adjust for that.

Nope, no check engine light and no hiccups. Thing runs/drives/sounds amazing.

@Jovi__ wow. Might have to look into this. Every other one generates a CEL after a while unless tuned.

@@esquared12 so far a month in, and I’ve done everything from interstate trips to backroad pulls and no hiccups. It’s doing great. K&N was slower than others to come to market, and I believe it’s because of the extensive R&D they’ve done to ensure a great product.

Glad you got some useful info from the video. Best of luck!

No, they work just fine as long as you buy the proper lug nuts.

@@SethKnows the hump hose?

@@Jovi__ The one with the hump in the middle that connects the red pipe to the box. Mine could fit completely inside of the red pipe easily.

@@SethKnows oh gotcha. I’ve seen some reports of kits shipping out with incorrect parts or missing hardware altogether. Thankfully mine was complete and correct.

@@lisonlili I probably will eventually. It’s claiming to add another 7hp and 11tq. I take that with a grain of salt tho.

@@Jovi__ it’s $250 same company seems like good gain. Money well spent

@@lisonlili I just looked and it’s actually $199 right now. They have a $50 off promotion. May have to just order it lol.

@@Jovi__ I saw it as well on the official website. Labor Day good deal on going

No CEL. They send a provision for that. So far, it’s been great.

I don’t think so honestly. I believe I read on the instructions that it’s not CARB compliant. I don’t know that for sure tho, you may want to check.

Thanks! Much appreciated! My whole purpose for making videos is to help someone that may be struggling.

You don’t need a tune, can be used as is. No check engine light either.

I recommend it.

You should!

There’s room to get your hand in there. You don’t need needle nose pliers.

Same. I’ve been holding out on buying an intake because I wanted to see what K&N was gonna offer. It does not disappoint. Great intake system.

Dang, no I was in a hurry to get the intake on and a video out that I didn’t think of that. I may film another video of the sounds, and I’ll be sure to get a bunch of different scenarios recorded.

Sounds great and one of the loudest I’ve heard. Not sure on heat soak because I haven’t had a chance to run it super hard yet. It definitely pulls harder. Maybe not the 18whp they claim, but does pull harder.

Haha you should see the exhaust welds on the top of the line Lexus $65,000 and over, absolutely no different. Car manufacturers don’t expect you to be showing off the underside of your car to your friends

no, this is a turbo car. I hate this bullshit about backpressure. No engine needs backpressure. As long as you have a good header it will take care of exhaust scavenging. Most engines make more power with an open header, think about that. Backpressure is bad. Of yourse you don't wanna have a 6 inch exhaust on a very small engine because the exhasut velosity will suffer, so xeah it is always a act of balance. But backpressure is bullshit, exhaust scavenging is real

​@@DeepRacer-zr4yp Darn that Toyota Chief Engineer Naoyuki Sakamoto when he talked about managing backpressure on the GR Corolla. I actually believed him! Now I look like a fool. I will never trust another experienced Toyota engineer no matter how many countless manhours they spend on engineering and testing the GR Corolla! 😶

Keng is correct. The car has the actuator for good reason. I'll take Toyota's design plans over folks who think this car is for drag racing.

I’ve been running it for several weeks now with no drawbacks. I work for a Toyota service department and have been checking/testing for any issues. So far, so good.
