Chevy Trailblazer BORLA Exhaust System Install w/ Sound Clips
Вставка
- Опубліковано 1 кві 2020
- Finally got around to installing the BORLA exhaust system that I found at my local auto salvage yard a couple videos back. This install should be the same for all Trailblazers, Envoys, 9-7X, and Bravadas equipped with the I6 engines. This system converts the restrictive factory single exit muffler to a more efficient dual exit system.

Maybe I need to be there but I don't hear a difference.
It actually sounded quieter with the Borla setup...
well he never mentioned anywhere or even implied that the sound of the exhaust would change all he said that borla claimed you would get a few gains out of it
he posted the audio probably so people can hear it does not alter the sound because pretty much thats what everybody was wanting it to do
🤣🤣 I hardly hear it
I have the same Trailblazer as you show on your videos I've installed the rough country lift kit and your video was a huge help i also installed ram air induction with jet tbody spacer again your video was the reason i installed it but on this video, alot of the fitting was left out your usually more detailed making your videos really would have benefitted from this one as its my next project wish you could have shown more. Im still a big fan so keep those cameras rolling.....
I apologize. This is one of my earlier videos. Some of my early videos weren’t as detailed as I thought they were 😅 But thank you for the kind words. I will hopefully get back to making videos soon! 🙂
I figured out what the cold air induction system is which was totally awesome that you did that ordered that for some reason it's taking a long time to come in but I want to try to do the dual exhaust too on my LS Chevy trailblazer thanks
Good luck with your installation. 👍🏼
I can hear the difference with a proper sound system, sounds good. Nice find, nice work, and nice video!
Thank you! I appreciate it! 🙂
Nah there isn’t a difference. Waste of time
I love our quarter of a million mile truck
Trying to drive past the moon on mine too 😆 (238,900 mi) :) currently just passed 200,000
We used to have a 2003 Chevy Trailblazer LS. Even the exact color. We got rid of it in 2011 because of bad rust
I have a 2003 LS it’s has 109k for mileage, and not a rust spot on it still looks new underneath as well, it’s been in western Colorado all it’s life, I used to live around Niagara Falls there you we’re lucky to get 2 years before your car was rusted out
cool exhaust mod. thanks
Thanks for watching! Please subscribe to the channel! 🙂👍🏼
bro the stock one had pops but the borla didnt hmm think about that
I could literally smell the exhaust when you started it up.
Lmao!
What's the model number on the cold air intake? I have a 2005 LS model and that cold air kit looks like a really nice fit! Great video thanks👍🏿
I’m not too sure of the model number. But it’s from Volant. I have another video with the Volant cold air intake install. Check out my Trailblazer content playlist and subscribe to the channel. It really helps! 🙂👍🏼
You found all those aftermarket parts specifically for your vehicle all at a salvage yard??? That's pretty rare, usually all those parts would have been stripped and sold before the vehicle even hits the salvage yard.
I did! I made a completely separate video of removing all the parts from the trailblazer in the junkyard. Link below 🙂👍🏼

This really helped me picking an exhaust
nice ill do the same my trail thank you
You’re welcome. Thanks for watching! 🙂👍🏼
I use single str8 pipe with cat to the back no issues after with more power.
That’s rad man. Thanks for sharing!
Nice junkyard find. Do you know the model number for this exhaust system for those who maybe interested in purchasing online?
Thanks, Angela! The link below is to Borla's website for this system. However, it has been discontinued so you will need to find a Borla retailer that may still have one on the shelf. I hope this helps. Make sure to Subscribe to the channel for future content! :)

Maaan what a junkyard score! my area never has anything like that lol
I was super stoked to find this! 😃
Hey man thanks for the vid. A couple questions.
1. I looked up the cold air intake from Volant, but they only have one for the 5.3L V8. Is that part maybe discontinued?
2. Did you end up getting it tuned? Did you have any issues with engine lights after the exhaust mod?
Thanks!
I believe the Volant CAI and Borla exhaust for the 4.2 models has been discontinued. Never got it tuned. No check engine lights and still running strong. 😃
@@PASSIONBUILT Awsome thanks for the quick reply! Do you think that throttle body spacer did much? I just got a TB and looking to do some mods!
No problem at all. Thanks for watching the videos! I honestly don’t think the throttle body spacer did much. Like I mentioned in that video, It’s a mod I would never pay for but it was free lol
The throttle body spacer does make this whining sound under acceleration which was annoying when I first installed it but I barely notice it anymore.
I got a 03 LTZ ,Kool
i just got me a 03 so i will like to do this but one question for yaa...
were the hell did u find that used and for how much???
At my local LKQ. The video I linked below shows all of the parts I found at the junkyard. 🙂👍🏼

Hey man I have same trailblazer and have high pitched noise not very loud by high pitch from the rear of my vehicle I believe it’s the fuel pump are they normally somewhat noisy it’s not crazy loud but seems to get louder in winter any advice helps. Awesome video
Thanks for the feedback! As for your high pitched noise. I would have to be there to give you a better answer. Fuel pumps on our truck shouldn’t be loud enough to hear while you’re driving. I only hear mine at prime and that’s it. If your pump is dying it could be louder than usual or if someone has upgraded the fuel pump to an aftermarket high flow pump like a walbro or deaschworks. It could be louder as well.
@@PASSIONBUILT appreciate feedback brother we trailblazing for life 😎💪🏾 Ima get it figured out and update with whatever I find when I do buts driving like a champ still for now filled tank today muffled noise quite a bit
What did you do with the 02sensor
It actually sounds quieter than stock... That's actually good! I hate loud vehicles.
It’s very mellow toned and I absolutely love that about this system. I already have a loud turbo Miata as a weekend car and I enjoy my daily to be quiet. It’s gives a very nice tone under acceleration that’s not annoying and overbearing. 10/10 would recommend this system to all trailblazer owners if it wasn’t discontinued.
sounds good
Thank you. Sounds much better under acceleration.
You front all them parts at a junkyard or did you order it..? If so I'm trying to do that to mines I have a 2005 Chevy trailblazer LT V8 engine tho I need that ASAP
All parts were found at my local auto salvage yard. Check out the video linked below. 🙂👍🏼

I noticed you didn’t weld the exhaust and you tighten it with a Rachet. Are the other exhaust options that you can do the same method without welding
Of course. There are plenty of bolt-on systems available.
Hey, question. Can you straight pipe a borla exhaust to get it louder? But still have the better fuel economy, and torque.
Honestly couldn’t tell you. 🤷🏻♂️😅
Not bad for a v6. Really could do a 5.3 swap and a 2/4 drop kit imo. Also maybe some 20s
It’s actually an inline 6. Swapping engines isn’t really an easy thing with these trucks. I already have lowered cars. Don’t want to lower my daily too lol
The 20s that came on the SS model trailblazers are nice but so expensive for a used set. I prefer the factory 16s with some meaty all terrains.
I sure would like a few snapshots of how your brush guard hooks too the frame I must be missing a piece for mine.... help
There are 2 brackets that bolt directly to the frame and then you bolt the brush guard up to those lower brackets as well as the 2 other smaller reinforcement brackets that go through the grille. I made a separate video called “Buying USED PARTS Can Save You HUNDREDS of Dollars!” and there is a short clip of me uninstalling the brush guard from the trailblazer that I removed it from. You can see the brackets I’m talking about in that clip.
@@PASSIONBUILT thank you so much I bought my grill guard off fb market place.. but didn't have the brackets ill watch the video get a screen shot of them maybe have some fabbed up thanks
No problem at all. Sorry I can’t help you more. But yeah you’re going to need to get a pair of the frame mounts first and then your brush guard will bolt up to them. Maybe you can get in contact with one of the companies that makes the brush guards and ask them to just buy mounts and hardware 🤷🏻♂️
i have a 2004 trailblazor and i want to customize it what should i do where do i start i want it to sound super cool
Hey there! First off, maintenance is key. Make sure all of your fluid systems are up to date. Intake, exhaust, and tune from PCM OF NC are common mods that a lot of Trailblazer owners do. If you want a louder exhaust system. Just look up available exhaust systems and read the reviews before ordering. I was super lucky to find the Borla system I have installed at the junkyard. Unfortunately it is no longer available for sale online. If you do come across one. I highly recommend. It is perfectly toned. 🙂👍🏼
Sound identical
Im looking forward to buy one of those trailblazers. Are they reliable?
Mine has been super reliable. I have had it since 164,000 miles and it just rolled 250,000 miles a few days ago. I have not had any major issues because I have maintained it since I purchased it and I believe the previous owner took good care of it too. As long as you keep up with the maintenance. It should be a reliable vehicle for you. However. I have heard of others that have had issues with theirs. Such as transmission failure or power steering issues. But if those systems are maintained. You should be fine 🙂👍🏼
I was able to buy one that was a garage baby with 70k miles on it. Its a 2004. I bought it 3 years ago and its been flawles. I like it so much that i sold my 2018 tacoma 4wd and kept the trailblazer. The tacoma had major electrical issues that the dealership didn't seem to care enough to fix. That 36,000 new bumper to bumper warranty means nothing to them. I will never buy another toyota ever again!
My family has a 2007 with 215k miles on it, it's had some power steering line issues but otherwise it's been pretty solid. Still runs and shifts great.
What vehicle did u get the exhaust system off from?
I mentioned it in the video. But if I remember correctly it was a 2004 Trailblazer.
What Borla system was used, I have a 03 LTZ I'm working on
I apologize. I don’t remember the part number. This exhaust system has been discontinued from Borla. If I find it. I will post it in the description and send it your way.
Can you buy this system online the thing that I've been trying to do is does a SS borla system work on a 2006 Chevy trailblazer as far as the resonator if I just bought the resonator and then built the system out from there because they don't have a complete kit but I do have a complete kit for SS wondering if it's the same thing
This system has been discontinued for a while unfortunately. The SS system is not the same. I’m sure you may be able to take it to an exhaust shop and have them make it work but it is definitely not the same.
what bola exhaust system is it? I'm look to upgrade my LTZ. exhaust.
This system is no longer available for purchase from Borla. I don’t remember the part number off the top of my head. If you look down in the comments other people have asked the same question and I have listed the model number in those comments. 👍🏼
Are you running the 5.3 or 4.2 engine in this?
4.2.
🧐I always wonder if these are emissions ready for smog check??
I honestly couldn’t tell you. I live in Florida. We don’t have smog checks down here. 😬
Same sound 😁😁😁, go with Magnago and you will skyrocket
In person the exhaust notes are noticeable. But for the price I paid for this system. I have no complaints. Also. I like the Borla tips way better than the Magnaflow tips.
what is the size of your tire buddy?
255/70/R16 and I am currently running the Falken Wildpeak AT3W tire. Hope this helps 🙂👍🏼
Did it even make a driving difference? Power torque etc?
There was definitely a noticeable gain in power. Nothing crazy. Probably could gain a little more with a tune.
Just got a 2007 trailblazer ls 70k miles on her been thinking of ways to improve fuel ecom
Only 70k miles? That’s amazing! If you keep up with the maintenance, it will last you forever! My Trailblazer is about to roll 250k and still going strong. As for better fuel economy. I would start with servicing the fuel system. Run a fuel injection cleaner, do a fuel induction system cleaning (sea foam), replace your engine air filter and then replace your fuel filter. Those maintenance services will help you improve your fuel economy.
@@PASSIONBUILT oh yeah I always have a can or 2 in my trunk haha I always do half in the tank and a quarter in the engine oil great for balancing the fluids out and allows the sludge to get beat up quicker and sink down for the oil change, I got a wining pully system that's causing the drive gear to rapidly vibrate so I'm gonna have them look at the tranny just in case we think it's just the master pully and the idle pully causing a bit of knocking with the engine when in idle
Where can i find that same exhaust setup ?
This exhaust has been discontinued for some time now. I found mine on another trailblazer in the junkyard. You might be able to contact borla to see if they can make this system for you though.
i have that chevy trailblazer but its 2009 model its LS MODEL I-6 engineFROM KUWAIT! BUT IMPORTED IT FROM KUWAIT TO PHILIPPINES BUT there is no spare parts here in the philippines i need to order it in the US so is it hard to find those spare parts?
We have an abundance of trailblazers in the local junkyards here in the states. There are plenty of part order sites as well that offer global shipping.
@@PASSIONBUILT so even in the year 2040 if my chevy trailblazer is still alive the parts of chevy trailblazer still available on that year even on junk yards in the US?
hello 👋
my name is Evgeniy. I want to ask you about the options for transmissions on a Chevrolet trailblazer. will you help me?
I have a couple videos up discussing Trailblazer transmission options and upgrades. The only realistic option is rebuilding your existing or buying a rebuilt 4L60E. I got mine from Detroit Axle.
You have your resonator and muffler reversed. Mufflers up front. There's literally tons of videos on the res delete
Thanks for your input 🙂👍🏼
How much you will charge to do my 06 trailblazer
Hey there. I apologize but I do not offer service work for others.
borla resonator make a better fuel mpg?
Not really to be honest. Didn’t change much.
Part number for the borla setup?
Hey there. The part number from Borla is 140006. However, this system has been discontinued. You might be able to get lucky and find one in the junkyard like I did or possibly find a used or NOS unit on eBay. I hope you can get your hands on one. It’s a beautiful exhaust system. Please subscribe to the channel and give the video a thumbs up. It really helps 🙂👍🏼
@@PASSIONBUILT thnks bro!
No problem at all.
If you cut the resonators off that are in the rear you'll get the sound you're looking for those are not mufflers just a useless trash cans , did it to my 03 trailblazer
Thanks for your input 🙂
I think in my opinion the borla was quieter the the stock exhaust
In the video. It does appear that way. But in person the Borla is louder and has a better tone. I apologize for the audio in the video.
I would love to do a transfer on my 06 LS 4200
A transfer? Like an engine swap?
stock is good as we don't want to add extra weight
I’m pretty sure the Borla system weighs about the same… 🤷🏻♂️ also looks much better than the factory exhaust.
He turned a storage unit into a shop 😂😂😂💀💀💀
Yes. Yes I did 🤷🏻♂️😂 I live in a townhome and don’t have a garage so I had to make due with what I could find 🤷🏻♂️
I actually upgraded from that 10x20 unit to a 20x30 unit within the same facility. The new unit is a lot more comfortable to work in and I have actually been able to work on my Trailblazer in the shop rather than outside. I’ve done a full suspension build and transmission swap in the new shop that I would have never been able to accomplish in the old unit due to size. I made a vlog showing the new shop last year when I moved. Linked below. Check it out. 🙂👍🏼

@@PASSIONBUILT that’s awesome 😎
For sure! Check out my other Trailblazer videos. Lots of fun and helpful content on the channel. Also, please subscribe if you haven’t already. I have a lot more Trailblazer and other Motorsport related content on the way 🙂
@@PASSIONBUILTI'm surprised they let you do that. Usually they call police on anyone that stays in a storage unit facility longer than 30 minutes. That's a constant thing in California. The manager on site will legit stare at you the entire time you're there at your unit. And continuously ask when you're leaving.
It’s a pretty common thing in Florida from what I’ve seen. I’ve had a few storage units and the storage facility has been cool with it. I’m no longer in a storage unit since I bought a house last year with a garage and I intend on building a full sized shop in my backyard. But the manager was super cool with me running my business out of the storage unit and allowed me to upgrade from a 10x20 to a 20x30. They didn’t mind as long as the facility was respected and no oil was spilled outside of the storage unit.
western state ? your TrailBlazer is commendably free of underside rust.
East coast. My Trailblazer has been in Florida all its life. I never want to deal with a northern car again. Rusty cars are no fun.
I want this on my 05 trailblazer lt come do it for me
Hey there. Unfortunately, these Borla exhaust systems are discontinued. But if you’re ever lucky enough to come across one. Buy it and take it to your local muffler man. They would be able to install it in no time at all! 😃
Anybody know the part number on the exhaust?
Nvm got it Borla 140006
It’s been discontinued for a while but you can find them from time to time.
@@PASSIONBUILT Yea all the websites say that, hopefully I can come across one at a junkyard too😂
Gotta cut off the res sounds like the factory exhaust
Nah. It definitely sounds better under acceleration than the factory exhaust. I need to make an update video on this with better sound clips.
Man why tf you hittin that camara so fast
Lol! It's just what I do haha
l couldn't hear any difference
Dont hear a difference time to chop off everything and run a straight pipe
Sounds better factory lol
Lol I promise it sounds so much better under acceleration. I need to make a follow up to this with a better mic. 😅
@@PASSIONBUILT lol! I rewatched it a few times and I’m like “damn factory slaps” lol 😝 I’ll take your word for it
Another dude just cut out the muffler and added a cherry bomb sounds like a Supra save the money and go with a cherry bomb and if you think about it a super is no different from this type of engine they run single exit exhaust
The engine in a Supra is completely different. Yes, it is an inline 6 engine but it’s not built the same. This Borla system was an extremely cheap junkyard find and I enjoy the look of the dual exit. If I never had found this system in the junkyard I wouldn’t have upgraded the factory exhaust at all. It’s honestly not worth it unless the deal is too good to pass up. Also, this is my daily. I’m not going for a noisy exhaust system. I have a turbo Miata for that 😅
Still sounds like a sewing machine.
🤷🏻♂️😅
Sorry bro but I cannot hear the difference.
Insert sawzaw here*
Didn’t have one at the time 🤷🏻♂️
Sounds literally the same lol
Thanks for your feedback but the sound in person is different. The microphone I had back when I made this video wasn’t able to capture the true sound of the Borla system. I’ll be honest and say that the Borla isn’t super loud or anything. But it’s very nice and toned. Much better over the factory system.
I’m surprised a Chevy Blazer is still running. They came out of the factory as junk.
235k miles and still going strong 🙂👍🏼
I agree with ya, my makes all kinds of noises and burns oil and the transmission slips like crazy, I’m at 199k miles.
@@MichaelFletcher-to7mm My 2004 has 223k and runs great.
Lol. Hardly made a difference in sound. 🤦♂️
In person it does sound significantly different. Sorry about the poor audio. I’m going to make another revised audio video with a better mic sooner or later.
sound the same to me no different I guess you trying to get that v8 sound
I can't hear a difference
The mic I used to record this video didn’t capture the difference that well. There’s definitely a difference. The Borla isn’t loud. But has a very nice tone under acceleration.
Waste of money big-time, should of spent a few more dollars on a Corsa Sport catback or at least thrown a couple of Dynomax Bullets on it.
I actually got this whole set from the junkyard and I think I spent like $60. It retailed for about $1,300 before it got discontinued from Borla. No money wasted. Never planned on upgrading the exhaust system on this truck but when I saw it at the junkyard I had to grab it. I think it was $60 well spent. 😁 check out the video below. It shows all the goodies I found that day at the junkyard and only spent $120 for everything I found.
ua-cam.com/video/U-HPlwmmNBU/v-deo.html
@@PASSIONBUILT the best thing about that expensive exhaust that you magically found for $60 is the T-304 stainless steel pipes. Try it with a Dynomax Ultra Flow X muffler and make sound exotic!
Nah. I’m good on that. I have a turbo Miata and motorcycles for that. Don’t need to make my daily loud too. 🤷🏻♂️😬
all that for the same sound... smh
Definitely sounds much better. The mic I had back then didn’t do this exhaust justice. But definitely a different tone especially under load.
No difference
There is definitely a difference. But the mic that I had at the time of filming this did not do a good job of picking up the sound difference. The most noticeable difference is under acceleration. At idle the exhaust system is very quiet and tone. It’s a great system and sounds fantastic under acceleration. Thanks for the comment though 🙂👍🏼
get a grip lmao
?
Sounds like crap before and after, good effort though.
Lol Thanks for the feedback!
