Engineered to perform in the most extreme environments. Constructed from mandrel bent 4 in. 409 stainless steel tubing for maximum flow; increased horsepower; increased torque; and lower EGTs. All systems use factory mounting locations providing stability and hassle-free installation. High quality OE style flange and band clamps are used for a complete 360 deg. sealing surface. A free flowing 24 in. muffler is used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque out of your rig. OE style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. The bayonet tip holds the hanger bushing in place for an OE style fit that does not change with time.
