Building a one off custom true dual is an art form! On this 2011 Mustang Gt 5.0 We started from the cats back building a 2.5 exhaust with a hydroformed x pipe a using our exclusive Race demon mufflers to give that signature sound that not many have. Finishing off this unique system we installed our elite 4-inch stainless viper tips. Carefully installing them to follow the cut of the bumper.
