Subaru WRX Exhaust Systems

Deliver on everything the Subaru WRX has to offer by treating it to a handcrafted MRT exhaust system made in the U.S. The WRX is already a premium performance rally machine with its high-output turbocharged engine and smooth handling - but it never hurts to have an edge. We're the leading designer of high-performance WRX exhausts and other accessories that are made in the U.S. With more than 35 years of OE and automotive engineering experience, the team at MRT knows sound.

WRX and STI Exhaust Kits

The Subaru WRX has been a compact sport leader for decades, and our selection reflects the many models still found on the road. We carry exhaust systems for the original standard Subaru Impreza WRX, the WRX STI sport model and the WRX VA series that first rolled out in 2015. There are separate designs for sedan and hatchback models - and we also have no-cat Subaru exhaust systems for owners whose sole focus are track days and competitions. Whatever generation of WRX you proudly drive, MRT has an exhaust kit that's a perfect fit.

Premium Sound and Performance

Experienced automotive engineers design every MRT Subaru WRX STI exhaust so it becomes part of the vehicle's DNA. We have cat-back and turbo-back WRX exhausts that are made of T304 stainless steel. The Street Race Cat-Back Subaru WRX Exhaust is the ultimate "happy medium" with a refined growl and strong horsepower boost that's street-legal in most states. Sport Touring exhausts are neighborhood-friendly while Extreme systems throw aside the restrictions in favor of a mighty roar.

For maximum exhaust flow and power gains, go with the No-Cats Turbo-Back WRX Performance Exhaust. It's a complete upgrade for track days, competition and private roads that will give anyone a jolt. Cat-back exhausts generate more sound while generally being less expensive and easier to install. Choose your new system based on what performance boost - power or sound - is more important to you and when your budget is.

MRT also sells replacement exhaust pipes that further modify the sound based on whether you prefer muscle car, turbo or sophisticated sport decibels in your eardrums. Subaru WRX Sport Touring Intermediate Pipe raises the decibels and adds depth while Street Race J-pipes make the stock cat-back more aggressive for off-road use. We also offer the JMS PedalMax; this WRX throttle controller increases response so the vehicle goes when you step on it. With so many performance solutions, we offer something that's right for where and how you drive.
