11-14 Subaru WRX/STI MRT Catback Exhaust
Un-cork your restrictive factory exhaust and get a sophisticated, deep note from your Subaru flat 4! This mandrel bent 3-inch system allows for an unrestricted exhaust flow enabling the car to breath freely, all while creating an aggressive, deep sound when on power. It's loud when you want it and more mellow when you don't!

While you will appreciate the new sound, the performance gains are real too. The increase in flow capability over stock reduces back pressure, freeing up horsepower and torque. And if you choose to make other modifications that generate more power, this system will compliment the upgrades. There is also a weight savings when installing the MRT exhaust system kit, which will help your car accelerate, brake and corner faster because lighter is always better!

Every MRT performance exhaust system is built right here in the USA from the highest grade 304 stainless steel, making it light-weight and exceptionally durable. Those who live in a corrosive environment will appreciate the superior rust resistant nature of this system. We are so confident of our build quality and materials that MRT stands behind every exhaust system with an industry leading LIMITED LIFETIME WARRANTY.

Not a fan of polished exhaust tips? MRT also offers the tips in this system with a matte-black Cerakote finish. Cerakote is a high temperature, durable ceramic coating that can withstand the rigors of high-performance driving. Since no polishing of Cerakote is necessary, they always look great!

Great Cat-Back! October 11, 2016

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.
