Is that the purr of a kitten or the growl of a tiger the WRX cat-back exhaust makes? Onlookers may argue about it, but this is one cat they won't want to mess with.

The MRT WRX/STI Sedan Street Race Cat Back has a loud, deep muscle car sound. We have handcrafted this Subaru WRX exhaust here in the U.S. of corrosion-resistant T304 stainless steel. That means it looks as good as it sounds and is built to last.

Base systems include T304 polished SS quad 4" tips and 3" mandrel bent tube. Black Ops black matte tip finish is available for an additional fee.

This system is engineered for the best sound to match your WRX/ STI and provides improved performance from the increased exhaust flow. The MRT Street Race Cat Back exhaust delivers enough elevated sound to get noticed and plenty of opportunities to feel the performance every time you put the pedal to the metal.

These WRX exhausts are packaged in a design without an excessive drone. The quad 4" tips will further separate you from the crowd. Whether you need a 2011 WRX exhaust or one for another model year, this cat-back will provide the sound, looks, and durability you want.

This product is designed for off-road, race use only.

Application: 2011 thru 2014 Subaru WRX and 2008 thru 2014 Subaru STI Sedan.

  • How does it sound? The MRT WRX/STI Sedan Street Race Cat-Back #92P112 has a refined, deep performance sound.
  • Is there drone or resonance? The drone is noticeable but tolerable.
  • What if I step on it? Wide-open throttle increases exhaust loudness and tone to an aggressive performance sound.

5 of 5 Great Cat-Back! October 11, 2016
Reviewed by: Corey West from Waterville, OH United States  
I have this on my 2011 WRX sedan shown in the video above.  It carries a lot of the characteristics of the full turbo-back with a touch less of volume when used with the stock down-pipe.  Fitment, quality and finish is superb!  I can't get enough of the quad 4" tips helping it to stand out from the crowd.  I highly recommend this to anyone looking to keep this OEM+ look, but enough grunt to show you mean business.
