MRT Extreme Axle Back Exhaust (91A152) - 2011-2014 Mustang GT & 2011-2012 GT500
Unleash the full potential of your 2011-2014 Mustang GT or 2011-2012 Shelby GT500 with the MRT Extreme Axle Back Exhaust. Built for drivers who want maximum volume and aggressive attitude, this system delivers a deep, commanding muscle car tone that makes a statement every time you fire it up.
Constructed from premium T304 stainless steel, this axle-back features 3 inch mandrel-bent tubing and a straight-through design to improve exhaust flow and reduce restriction. The result is stronger throttle response, increased performance, and a more responsive driving experience. Dual 4 inch double-wall stainless steel tips provide a bold rear appearance, with an optional Black Ops matte finish available for a more aggressive look.
As the loudest axle-back option in the MRT lineup, the Extreme system is designed for enthusiasts who want their Mustang to stand out at all times. Despite its aggressive tone, MRT engineered this system to keep drone at a manageable level for better drivability. Installation is simple with a direct bolt-on design that requires no tuning, making it an easy and impactful upgrade.
