Ford Mustang GT S650 Valved Sport Exhaust System
Welcome to a revelation in the world of S650 exhaust sound. When doing headers, these cars can get extremely raspy and unruly. With the Valvetronic Designs valved exhaust system we have designed the perfect sound experience with a center resonator in order 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. 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.
