Description:

The S650 Mustang GT is the most advanced Mustang yet—but when paired with headers, its soundtrack can become overly raspy and unrefined. Valvetronic Designs set out to perfect that sound. After extensive R&D, Valvetronic Designs has engineered a 3.0-inch valved exhaust system featuring a center resonator that tames unwanted rasp while unleashing a raw yet smooth tone that’s pure driving joy. Whether connected to factory manifolds or adapted for aftermarket headers, this system is designed to bring out the best in your Mustang’s V8 character.
