Details & specs

Unleash a Race-Inspired Sound

Give your 2018-2026 Mustang GT the aggressive, race-ready sound it deserves with the Roush Performance Cat-Back Exhaust System. Designed specifically for 5.0L V8-equipped models, this system delivers a deep, throaty rumble at idle and a fierce, high-performance tone under acceleration—turning every drive into a statement.

Unlike stock systems that restrict sound and flow, the Roush Cat-Back system is engineered for maximum performance and an exhilarating acoustic experience. With a straight-through muffler design and mandrel-bent 304 stainless steel tubing, this exhaust enhances horsepower and torque while maintaining a refined tone during cruising.


Aggressive Quad-Tip Design with Stealth Black Finish

This kit features quad 4-inch exhaust tips finished in a sleek black coating, delivering an aggressive look that perfectly complements your Mustang’s rear fascia. Each tip is etched with the iconic Roush “R” logo for a signature touch of performance. This system is compatible with factory valance designs that accommodate quad tips but is non-active, offering a consistently bold sound profile without the need for valve integration.


Precision-Engineered for the Perfect Fit

Like all Roush Performance products, this cat-back exhaust system is rigorously tested and validated to meet the highest standards of fitment, durability, and performance. CAD-engineered for a direct bolt-on installation, it includes everything needed for a hassle-free upgrade—no cutting or welding required.


Built to Perform. Backed by Roush.

Constructed from corrosion-resistant T304 stainless steel, this system is built to withstand the elements and deliver long-lasting performance. Whether you’re carving corners or cruising the freeway, the Roush Cat-Back delivers unmatched sound and quality backed by Roush’s Limited Lifetime Warranty.
