FTK hands the Shelby over to Corsa for the installation of their new DB muffler for high horsepower cars like our 07 Shelby. We all know the obnoxious sounds that come from this beast after you install full length headers and high flow cats along with over 730hp. I don’t think it could have been said better then how Ray put it….. ““We decided to give Corsa the ultimate challenge, give our Shelby a low deep tone at part throttle, a race car sound at wide open throttle, remove the drone we experienced with every single muffler on the market, and do all of this without sacrificing power. Since the install of our full length headers, we have tried every muffler on the market and have been unsuccessful in finding the perfect balance between good sound and no drone. Corsa came up with a set of mufflers that placed the bar way above what any other manufacturer can reach. Perfect balance was achieved in the first try, what else would you expect from Corsa”  -Click here to see the video-
