Rated 5 out of 5 by from Subaru SS 3" Downpipe I was surprised how well this pipe breathes! Power increase is obvious and fitment is spot on. Very stealth in the sound department with a stock muffler but still a very noticeable back pressure reduction. I chose this pipe for the quality I've seen in all of Cobb's products but also for the other not so obvious features. For example, the welds between the casting and the stainless extrusion have more than double the welded surface area of the competitors pipe. The cat is down low and keeps the under-hood temps down. Should I ever need to replace the cat, its location under the car makes replacement (at any reputable exhaust shop) easy.

Rated 5 out of 5 by from Thoroughly impressed with this system The pictures do not do this exhaust system justice. It is beautiful, with impressive welds. It is as much a work of art as an upgrade to the car. It is actually a shame that most of it is underneath the car, and remains unseen. This was surprisingly easy to install, and fit perfectly. I was more than happy with the new sound this exhaust produces. though louder than the factory exhaust, it has a very nice growly rumble to it, and as promised in the description, it is not an obnoxious noise you so often hear from other after market systems. I highly recommend this one, and only wish I had upgraded years ago!

Rated 5 out of 5 by from Perfect I've had this exhaust for the last month. I commute every day to work and have a 1 year old so super loud and drone were out of the question. This exhaust is awesome. Perfect sound with no drone. I can hear it but nothing like some of the other exhausts for the Rex. Sounds awesome at WOT.

Rated 5 out of 5 by from Sounds Sooo Goood Installed this on the 2018 WRX. Everything about this exhaust is true quality. The welds are perfect, the fitment spot on. Did it in the garage by myself in about an hour.(Silicone the hangers and take them off the factory hanger instead of the exhaust. No tools needed just pulled them off and slid back on). I like low profile so Resonated was the way to go for me. If your only doing Cat Back and want to be heard do Non-Resonated. I have the J Pipe and Hi Flow Cat sitting in the Garage waiting for a Turbo stud kit( just in case). I'm sure their going to hear me too.

Rated 5 out of 5 by from Cobb TBE 06 WRX I purchased the Cobb turbo back exhaust for an 06 WRX directly from Cobb. The quality of construction is fantastic. The weld work is beautiful, perfect uniform scallops. Fitment is also perfect. Sound Quality is very nice, very deep rumble. Slightly louder than I was expecting at less than WOT, but very tolerable. The one downside to the TBE complete kit is the lack of the doughnut gasket that connects the downpipe to the centerpipe (two parts supplied by Cobb). This is soposed to be reused, but on my car, the gasket was completely destroyed and could not be reused. I'm guessing that on newer cars this would not be an issue, but this gasket is not stocked by any of the national chain autoparts stores and is only stocked by dealership parts departments. The gasket is of nominal cost compaired to the cost of the TBE system and I feel that since this is a complete TBE system, it should include a new gasket to connect all the parts in the kit and not reuse the one from the vehicle. Even with that one complaint, the is an excelent system and when paired with an accessport, really opens up the potential of the engine.

Rated 5 out of 5 by from Amazing sound Hello from Russia, Moscow. I installed on my STI my05 this exhaust with. A quiet ride beats on the ears, but if you depress the accelerator pedal to the floor, the sound is incredible, and if you go in the tunnel - breath-taking! thank you!
