Welcome to a revelation in the world of S650 exhaust sound. When doing headers, these cars can get highly raspy and unruly. With the Valvetronic Designs valved exhaust system we have designed the perfect sound experience with a center resonator to lower rasp levels and deliver a raw but also smooth sound for the ultimate enjoyment. This system measures 3.0 inches all the way back to the tips. This system bolts up to the factory exhaust manifolds but can also be adapted to fit aftermarket headers. Utilizing vacuum valves ensures this system will last, as vacuum valves are far more robust and reliable than the electronic ones supplied by the factory. Our research and development over the past 6 months on this system has led us to the ideal sound experience for the S650 GT Mustang platform.

Crafted with precision engineering and cutting-edge technology, this exhaust system is designed to elevate your driving experience to new heights. Unlock the full potential of your Mustang's V8 engine with the Valvetronic Exhaust's advanced valve control mechanism. Seamlessly switch between different modes – from a refined and subdued street mode to an aggressive and exhilarating track mode – all at the touch of a button. Whether cruising through city streets or tearing up the racetrack, this exhaust system allows you to tailor the sound and performance to suit your driving style.
