Installation Instructions

The MRT WRX/STI Extreme Cat-Back has a loud, deep muscle car sound and is handcrafted in corrosion-resistant T304 Stainless Steel. Base systems include T304 polished SS quad 4" tips and 3" mandrel-bent tube. Black Ops black matte tip finish is available for an additional fee. This system is engineered for the best sound to match your WRX/ STI and provides increased performance from the increased exhaust flow. The MRT Extreme has enough elevated sound to Get Noticed, plenty of opportunities to Feel the Performance, and packaged in a design without an excessive drone. Combine this system with the MRT Performance J-Pipe without Catalyst and the MRT Performance Mid-Pipe to get a full 3-inch system from the turbo to the tips (WRX only). No tune required.

This product is designed for off-road, race use only.
Application: 2015 thru 2021 Subaru WRX and STI. Designed to fit stock J Pipe.

Hear the Difference

How does it sound? The MRT WRX/STI Extreme Cat-Back #92P114 to stock downpipe has a balanced, deep muscle car sound.
Is there drone or resonance? The drone is noticeable but tolerable.
What if I step on it? Wide-open throttle increases exhaust loudness and tone to an aggressive performance sound.
