Subaru 3" Turboback Exhaust Titanium (Resonated J-Pipe) WRX Sedan 6MT 2015-2019 is rated 4.9 out of 5 by 9.
Rated 5 out of 5 by from Outstanding Fabrication and Fit I just installed the resonated J-pipe for my 2015 WRX. The materials, fabrication, and fit of the J-pipe are outstanding. Connected to the Suburu accessory STI cat-back system, the total exhaust sound is outstanding with no annoying resonances at any speed/rpm. I installed the Cobb Mishimoto CAI/Cobb TBE 93, stage 2 map and am look forward to running a few datalogs after the ECU settles to get a true reading on added performance in near future. I settled on the Cobb TBE after doing much research and shopping and am very pleased.

Rated 5 out of 5 by from Reduce The Rasp I originally had the COBB J-Pipe Non Resonated, but had a fitment problem and COBB replaced it with the resonated version per my request. I had quite a bit of rasp with the original J-Pipe. With the resonated version, it reduces the rasp and makes the car sound much more attractive. As with my other review, I highly suggest purchasing OEM Turbo Studs, Bolts, and Gasket as the nuts will strip out on you. I prefer this pipe over the non-resonated if using the stock Cat-Back.

Rated 4 out of 5 by from 2017 WRX, great product, nightmare install After I installed the AP and Big SF on my 2017 WRX at 10k miles, it wasn't long before I decided to do the resonated j-pipe. The product delivered fast and as always Cobb quality is excellent. Before you start the removal of the stock j-pipe do a lot of research and make sure to purchase a replacement turbo bolt stud kit. This is a must. Im surprised this wasn't included by Cobb since its likely these will be needed as part of the headache to remove the stock set up. I started my install by driving the car on ramps and removing the plastic tray and skid plate. Relocating the ground wire and removing the metal j-pipe braces was easy. Only use 6pt sockets for this project or you will have issues. The nuts that hold the j-pipe to the turbo are self tightening and were incredibly difficult to remove, even when using penetrating oil. I had to fight with this step for about 2 hours. The bolt on the bottom left of the turbo was seized and ended up pulling out the bolt stud. The bolt on the top right is almost impossible to reach. For this I had to use 2 extensions, a universal, and deep well 6pt. After 30 minutes I was able to make solid contact with the nut. Yay! Of course since the nut was practically welded on the the bolt stud as soon as I gave it force it rounded the top. Ugh. Total pain. I was able to remove all hardware EXCEPT the top right bolt. About 6 beers later, I decided it would be better to just throw everything back on the car and take to my buddy (who is a mechanic). Putting everything back took about 20 minutes and was very simple. My friend's shop was able to remove everything (even the mangled top right bolt) and install the new pipe in about an hour. Given this, I would have taken to him from the start. Probably helped that I loosened everything up for him. "First time tight, second time alright". Right now I am driving around with 3/4 turbo bolts secure since we're waiting on the aftermarket bolt stud kit to deliver. No exhaust leak, but Im going to take it easy until I have all 4. Before I hit the road I updated my car with the new Cobb Stage 2+ Big SF map and WOW. I am very happy with the performance gains with this new set up. My goal was faster, not louder. This resonated j-pipe is great and provides much better response and power. I was actually surprised with how much I like the sound paired with my STI catback exhaust. When cruising its barely louder, until you stomp on it. On heavy acceleration you can definitely hear the difference. The tone and noise created fits well with the car and doesn’t sound like a slammed 93 Civic. The sound clips online do not give the Cobb j-pipe justice. Better instructions, setting expectations for DIY installation, and including a replacement turbo bolt kit would have made for a better customer experience.

Rated 5 out of 5 by from Titanium catback exhaust on 18' STI I just finished the install on my 18' STI and I can't say enough great things about this exhaust. This catback is absolute top notch, the build quality is incredible, it sounds phenomenal and it looks stunning! Is crazy how light this system is compared to other SS catbacks. Coming from a different catback brand, I can say the drone on this exhaust is much much less, almost stock like.

Rated 5 out of 5 by from Nice gurgle, popping at high-revs. So the Resonated J-pipe is 100% the way to go if you are looking for that low key, but ready to rumble exhaust sound. The exhaust notes are noticeable. In every gear revving the engine out to nearly 7k you will get an awesome popping gurgle sound. Amazing!!!! Also at red lights, pressing the gas to about 4k will also make the same sound on decel. I thought I left something loose and was having an exhaust leak. I am pretty OCD and checked 2 consecutive days just to make sure I wasn't crazy. The craftsmanship: what can I say. It is built with precision and truly out ranks the competition. The only downside is the accuracy of how the two sections line up, including the gasket. Its pretty good, not superb but it will do the job without any issues. The studs: be careful. Take your time. Mine came off without breaking nor stripping any out. I also used PB Blast. The O2 sensor attachments are without a doubt perfect. Overall this product is 10/10 in every category.

Rated 5 out of 5 by from Great improvement This pipe plus the stage 2+ map made a nice difference. My turbo flutter is gone. I already had the air intake and the cat back system so I figured why not. Nice sound improvement but not obnoxious. I love the craftsmanship of these products.

Rated 5 out of 5 by from Amazing Quality Installed this on my 2019 STI and could not be more pleased. The sound is PERFECT and is what an STI should sound like... perfect rumble without being annoying. Not only that, this exhaust looks incredible. The craftsmanship is top notch, which made install a breeze. Was able to install this solo in about an hour with no fitment issues. Could not be more pleased. Thank you Cobb for always delivering.

Rated 5 out of 5 by from The Best sounding exhaust by far I just got done with installing this exhaust onto my 19 STI and wow it sounds absolutely incredible. I'm running Nvidia catless downpipe and so with that combination it is very loud but certainly doesn't drone. Cruising you can hear the exhaust but it isn't too loud that you couldn't have a conversation with a passenger on the highway but open her up and wow people certainly know that you are coming! Love love love this exhaust!!!
