Ford Mustang GT S550 Valved Sport Exhaust SystemWelcome 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.

Not even close on the size
Size: 3X-Large, Color: White
Size is not even close to correct. Ordered a 3xl but the actual size was closer to a XL or even a large. Be wary on the sizes. They are not accurate

Fairly good quality. Hubby wore this as fun alternative to his regular tux in a cruise elegant night. Looked sharp and we even got family pictures in it.

Bought this for my son's junior prom and it looked so good on him. I had to get a few alterations done because it was a bit too big for him but all in all great quality for the price.
