The COBB Cat-back Exhaust is a triumph in design and execution that provides performance like no other. 304 stainless steel is used throughout the exhaust construction. All components are meticulously TIG welded for outstanding appearance and strength. Four custom exhaust tips fill the factory bumper cut-outs perfectly, protruding just enough to show off the COBB logos etched into the top of each polished tip. Also features a COBB stamped logo on the underside of each muffler.


The long awaited COBB Cat-Back Exhaust for the 2011+ Subaru WRX/STi Sedan. This mandrel bent exhaust uses twin straight-through mufflers terminating in beautifully laser-etched 3.5" quad-tips to make your presence known in the way that only COBB Subaru exhausts can provide. The outstanding craftsmanship and attention to detail are evident in every aspect of this gorgeous cat-back.

Subaru Cat-Back Exhaust STI Sedan 2011-2014, WRX Sedan 2011-2014 is rated 4.6 out of 5 by 9.
Rated 5 out of 5 by from awsome quality! Lets just say that I have been going back and forth between the cobb and the Q300 for about a year now. And final made my decision and couldnt be happier. The videos on line of the Q300 just sounded to "Tinny/Raspy" for my taste. The cobb is more of a throaty sound, which is great. If you want that nice deep tone/rumble, then get this exhaust! I have this paired with a invidia catted downpipe, just sounds awsome! Not loud and overbearing, great for a daily driven car. Build quality was excellent and no fitment problems at all, which makes this ideal for a one person install. Thanks Cobb

Rated 5 out of 5 by from IMO Best Sounding Exhaust This exhaust has to be one of, if not THE best sounding exhaust for the STI sedan that is made. The exhaust tone is deep and throaty and has no "pingy" sound at high RPM. There is no drone at 60-80 mph while in 6th gear driving on the highway. Its super sexy too. Sticks out just enough, and hangs perfect with the stock hangers.

Rated 1 out of 5 by from Wish I never bought it! The pipes are extremely thin, the mufflers are very, very heavy and restrictive! The bolts and gaskets are garbage from China and the flanges are easily the worst I've ever seen. With a MSRP of $1,300.00! I was expecting top quality but in fact was misled by Cobb, I'm completely disappointed with what they claim is quality and will never recommend, install or buy another Cobb exhaust system product ever again. The sound isn't anything special and compared to any other brand, the Cobb catback is a waste of money. DO NOT LET THE OTS MAP NOTE'S INFLUENCE YOUR EXHAUST SYSTEM PURCHASE, YOU OFTEN NEED A CUSTOM DYNO TUNE AT STAGE 2+ AND DEFINITELY AFTER STAGE 2+ REGARDLESS! Buy a custom exhaust or pretty much any other brand instead, even an Ebay exhaust is better then a Cobb exhaust. This product has me avoiding anything made by Cobb. If I could get all of my money back I would in a heartbeat but their return policy, even with a new unused product is scandalous.

Rated 5 out of 5 by from Perect purrr! Just installed this exhaust on my 2012 WRX sedan. Very easy to install (hardest part was getting my old, rusty one off!). Absolutely love the nice Subie rumble I have now! Not obnoxiously loud ( I like my neighbors) but, has the distinct purr we know and love

Rated 5 out of 5 by from 2014 WRX sedan I bought my exhaust about a month ago I'm really happy with it! It's not loud but has a deep tone exactly what I was looking for for a daily driver". Also I have the downpipe as well so I noticed a good power game
