2015-2021 Subaru WRX MRT Street Race J Pipe Exhaust

If you have a WRX solely for racetracks and off-road adventures, our Subaru J-pipe exhaust is one of the easiest, most affordable ways to turn heads. The 2015-21 MRT WRX Street Race J-Pipe Exhaust system is designed for off-road race use, has no catalysts and gives an aggressive, muscle car sound plus a louder turbo sound. MRT engineered this system with the best sound to match your WRX. It also provides increased performance from the increased exhaust flow, producing more horsepower, better throttle response and more efficient fuel use. You'll be louder and more powerful on the track, letting you drown out the competition as you leave them behind.

High-Performance Exhausts with a DIY Design

The MRT Street Race series has enough elevated sound to Get Noticed, plenty of opportunities to Feel the Performance and is packaged in a design without an excessive drone. Each Subaru WRX VA J-Pipe Exhaust is handcrafted from corrosion-resistant T304 stainless steel with three-inch mandrel-bent tubing. A straight-through muffler design further increases the exhaust flow. As a Street Race exhaust, it gives your vehicle a more aggressive edge than the Sport Touring system. Watch our video below to hear how this unleashes the decibels that have been waiting inside your sport compact machine.

All Subaru WRX MRT exhaust systems are made in the U.S. and backed by a limited lifetime warranty. You can install your 2015 WRX exhaust system in a home garage, the driveway or even the backyard. All you need is an hour and standard hand tools such as ratchets, wrenches and a flathead screwdriver. It's the ultimate weekend project for a Subaru enthusiast. You don't even need to do a post-installation tune - though you can if you want to wring every bit of performance from your machine.

This is a non-catted J-Pipe Downpipe replacement exhaust piece intended only for tracks and non-public roads. It will fit all standalone first-generation Subaru WRX VA models produced from 2015 to 2021 (not the Subaru WRX STI). If you want an even bigger performance upgrade, pair this downpipe with the 2015-2021 Subaru WRX MRT Extreme Cat Back Exhaust #92P117. For a mellower, street-legal sound, consider the 2015-21 Subaru WRX Sport Touring Intermediate Pipe. We also offer standalone cat back and turbo exhausts as well as systems that will fit the WRX STI high-performance variant.
