MRT Engineering 11-14 Subaru WRX/08-14 STI Sedan MRT Version 1 Cat-Back - 92P112

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 Version 1 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 increased exhaust flow. The MRT Version 1 Cat-Back is louder than the Version 2 but quieter than the Version 3. It delivers enough elevated sound to get noticed and plenty of opportunity to feel the performance every time you put the pedal to the metal.

These WRX exhausts are packaged in a design without 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.

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