Ford engineers did an incredible job at coming up with the new active valve dual exhaust system that delivers a throatier engine sound. What makes this possible is "A new three-inch equal-length exhaust system features a patent-pending built-in X-pipe, unique “trombone loop” and first-for-Raptor active valves. The system takes advantage of a true pass-through muffler design that improves sound quality. Customers can configure four sound level modes – Quiet, Normal, Sport and Baja.
