Ford Mustang GT S550 – Valved Exhaust System
Clean Tone • Adjustable Sound • R&D-Tuned for the Perfect Mustang Note
A New Era of Mustang Sound
The S550 Mustang GT is an icon of American muscle—but when fitted with aftermarket headers, the sound can become harsh, raspy, and unruly. Valvetronic Designs has created the definitive solution: a valved exhaust system engineered to deliver a smooth, refined, yet aggressive tone worthy of the Coyote V8.
By integrating a center resonator, our system tames unwanted rasp while preserving the deep, muscular character Mustang owners crave. Whether paired with factory manifolds or adapted to aftermarket headers, this is the exhaust that finally gets the S550’s soundtrack just right.
