Make Your Hatchback Sound Big

Every WRX/STI hatchback exhaust system we sell is handcrafted in the U.S. from T304 stainless steel three-inch tubing and a straight-through muffler. This aircraft-grade material is mandrel bent, giving it ultra-smooth walls for the highest possible exhaust flow. As a 2008-2014 Subaru WRX STI cat back exhaust, it offers more horsepower gains than an axle back system for people serious about performance. We inspect it a minimum of four times before shipping to confirm it meets our quality standards.

This system fits the 2008-2014 Subaru STI Hatchback or the 2011-14 WRX with simple DIY installation. As part of the MRT Street Race series, the system is built for people who are serious about all aspects of their track car performance. It only takes about 90 minutes and doesn't require tuning! The quad tips come standard with a polished stainless steel finish. For added style, consider a matte black exhaust tip finish that will give competitors a great view as you blow past.

Muscle Up When Going Off-road

Drivers who own a Subaru Impreza WRX or WRX STI already know how capable a compact car can be of big things. Adding a 2011-14 WRX exhaust to the mix only further elevates this machine. You'll feel even more like the king of the rally world while getting a healthy dose of classic V8 muscle car stirred in.

Whether on pavement or gravel, the 08-14 WRX Hatchback Cat Back Exhaust is ready to help fuel your quest for speed and sound.
