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.

DO NOT BUY UNLESS YOU WANT SPOTTY-BLOTCHY PIGMENT ISSUES! I used the product one time, and got terribly fried/burnt and when the burn healed my skin got very cheetah print spotty blotchy like. Now I am using prescribed cream my dermotologist prescibed to try to heal the pigment issues this product caused. this product is a thick oil, NOT SPF 45-- TRUST ME you do not want this!!! See pictures i'm attaching to this review.

I really did light the way it feels nice and thick.Creamy sparkly, but unfortunately there are cheaper products out there than this.That can probably do the same job
