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.

Best investment ever
By Kevin May 1, 2018After 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.

Perfect
By Ron September 11, 2017I 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.

This Exhaust is Awesome
By Deez June 4, 2015The 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..
