2015-2017 Ford Mustang 5.0L GT Fastback - 3" Single Exit Catback Exhaust

2015–2017 Ford Mustang GT 5.0 Coyote Catback Exhaust System

The 5.0L Coyote is one of the best sounding V8 engines ever built. The Thermal R&D Catback Exhaust was engineered to bring that sound to life without the cabin drone that comes with many aftermarket exhaust systems. Designed specifically for the 2015–2017 Ford Mustang GT, this system delivers an aggressive exhaust note, exceptional build quality, and everyday drivability.

Most performance exhaust systems force you to choose between an aggressive sound and long-distance comfort. We don't believe you should have to compromise. Our proprietary True Helmholtz Technology eliminates the frequencies responsible for cabin drone while preserving the deep, unmistakable tone the Coyote V8 is known for. Whether you're carving canyon roads, cruising the highway, or enjoying a weekend drive, you'll hear the difference every time you press the throttle.

The result is a deep, aggressive exhaust note under acceleration and a refined driving experience while cruising at highway speeds.

Installation is straightforward using the factory mounting points. No cutting, welding, or permanent modifications are required, making this a true bolt-on upgrade that can be completed with basic hand tools.
