2008-2014 Subaru WRX Hatchback MRT Turboback Exhaust
Un-cork your restrictive factory exhaust and get a sophisticated, deep note from your Subaru flat 4! This mandrel bent 3-inch cat-less system allows for an unrestricted exhaust flow enabling the car to breath freely, all while creating an aggressive, deep sound when on power. In order to tame this tone at cruising speeds, we include our unique drone management system which ensures a more comfortable cabin experience for enthusiasts. In other words, 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 significant 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!

Up the fun factor of your Subi with great sound and more power!

MRT recommends a custom tune when replacing the factory downpipe.

Overall fantastic exhaust October 16, 2017
Reviewed by: Jake Mantz from Colorado Springs , CO United States  
Just installed and was a very easy install in all honesty. Mounts right up to all stock compenents which is fantastic. I Like the fact that everything in the rear that you can see is polished to look good for visual appeal. Sounds amazing, one of the biggest reasons I bought it along with being one of the only products to still have the quad tips. These guys really did an amazing job at designing and perfecting this exhaust, especially the drone management technology. It really works and stays subtle at idle and lights after warmed up and then sounds like a complete beast at wot or even just going through the rmp range. And a big shoutout to Josh in the sales department for helping me out constantly with all my random questions. Can't wait to work with you guys more in the future.

Best Subaru Exhaust! October 11, 2016
Reviewed by: Corey West from Waterville, OH United States  
This is by far my favorite exhaust available for the 08-14 Subaru.  It is tame when it needs to be, but a monster at WOT.  The quad 4" tips also make it stand out from the rest of the crowd.  With the high quality of materials and craftsmanship I'll driving this exhaust for a long time.  I've also paired the full turbo-back with an external wastegate for the ultimate of fun.  I highly recommend this exhaust to anyone looking for the looks, sound and performance from their Subaru.
