Ford Mustang GT S550 Valved Sport Exhaust System
Welcome to a revelation in the world of S550 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 clean and smooth sound for the driver and passers-by. 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 S550 GT Mustang platform. It's time for you to make your S550 sound as it always should have.
