304 stainless steel is used throughout the exhaust construction. All components are meticulously TIG welded for outstanding appearance and strength.

Perfect fitment is achieved with either the Subaru factory downpipe or the COBB 3" SS Downpipe.
The COBB 3" SS Cat‐back Exhaust for the 2015 Subaru WRX/STI is a triumph in design and execution. Install the COBB 3" SS Cat‐back Exhaust on your WRX/STI and experience performance like no other.

Great Choice !
After doing some research and reading other reviews, I decided on this system because I wanted more sound (but nothing excessive) and no droning. THIS SYSTEM DELIVERED ON ALL MY EXPECTATIONS. Before install, I sent it out for a black ceramic powder coat finish that is heat resistant to 1800° F and purchased the recommended COBB Urethane Exhaust Hangers. I highly recommend this process if you plan on painting the mufflers or tips, as it will not peel or flake. Cost for ceramic powder coat for entire system (CAT back) approx. $225
Best investment ever
After much research I finally pulled the trigger of this cat back. At first I thought the price was a bit high, but after installing and hearing this run on my stage one map I was smiling ear to ear. It fit likes a glove. Can’t wait to go stage 2+. Thanks again subispeed.
I had the ETS system on my previous STi and I loved it! However, it was just a little too loud for my liking. I switched to the Cobb and it's perfect. I bought the Cobb hangars and everything sits how it should. This system will not draw unnecessary attention. It's very deep. It may not be as aggressive as some would like.
Great exhaust not to loud and sounds clean. I've had this exhaust for a long time now and I love it !
This Exhaust is Awesome
The Cobb Stainless Steel 3" Cat Back Exhaust is awesome. The quality is incredible and the sound is exactly what I wanted.. It has a deep tone and is not too loud.. I did not want a loud cat back setup and this is the perfect balance. You will want to jack up your car to polish the entire exhaust, that is how nice it is. I would recommend ordering the Cobb Urethane Exhaust Hangers with your new exhaust. The stock hangers will work but to keep the exhaust snug spend the extra dollars. They are Cobb part # 511312. Also the customer service from SubiSpeed was great.. I must have searched for 5 days trying to figure out what exhaust to get, watching youtube videos reading forums and I was completely undecided. Then I emailed SubiSpeed customer service and -Yo helped me make my decision. So if you are like me and cannot make up your mind on what cat back to get.. I don't think you can go wrong with the Cobb... And SubiSpeed.com will ship it out quick..
