The aFe POWER MACHForce XP Cat-Back Exhaust System (part number 49-44002) is engineered as a direct-fit upgrade for the 2006-2007 GM 6.6L Duramax.
The new MACH Force XP exhaust is engineered to perform in the most extreme environments. This system is constructed from mandrel bent 4 in. 409 stainless steel tubing for maximum flow; increased horsepower; increased torque; and lower EGTs. MACH Force XP exhaust systems are the perfect combination of performance; fit; and value. All systems use factory mounting locations providing stability and hassle-free installation. High quality OE style band clamps are used for a complete 360 deg. sealing surface. A free-flowing 24 in. long 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.
