    Description

    Improve Performance and Sound. A MAC Performance Axle-back Exhaust System will add a throaty muscular exhaust note to your EcoBoost powered S550 Fastback Mustang and improve it's performance at the same time. By reducing back pressure with a free-flowing exhaust, you will see rear wheel gains in both horsepower and torque.

    Flow Path Mufflers. MAC Flow Path Chambered Mufflers feature a patented multi passage design, following Helmholtz's Theory of Tone, to produce a muffler that effectively flows exiting exhaust gases all while maintaining a desirable tone. With no packing that can burn out, Flow Path Mufflers will sound the same mile after mile, year after year.

    High Quality Construction. Constructed from mandrel bent stainless steel tubing for superior strength and corrosion resistance, this MAC Performance Axle-back Exhaust features two "Flow Path" chambered mufflers that end with massive 4" diameter polished stainless steel slant cut exhaust tips for impressive muscle car looks and sound.

    Cut & Clamp Installation. The installation of this Axle-Back Exhaust system will require cutting and removing the factory muffler assemblies and clamping the new muffler assemblies in place. Clamps and instructions are provided.

    Application. This MAC Axle-Back exhaust system is designed to fit the 2015-2020 EcoBoost Fastback Mustangs without the Active Valve Exhaust. Not compatible with convertible models.
