aFe 2004-2007 GM Silverado/Sierra 1500 4.3/4.8/5.3L 409 SS Catback w/ Black Tip

This system fits all V6/V8 engines and produces an astonishing 9 HP and 15lbs. x ft. torque at the wheels. The cat-back design is constructed using 3" mandrel-bent 409 stainless steel, free-flowing muffler, OE style bayonet hangers, band clamps and all hardware necessary for a hassle-free installation. The smooth curves and increased diameter of the exhaust system helps remove horsepower robbing restriction and keeps exhaust gas flowing smoothly for increased horsepower and torque. The system is finished off with an aggressive black 304 stainless steel, rolled slash cut tip for an aggressive style.

Installation is a Snap: This MACH Force XP uses all factory mounting locations providing stability and a hassle-free installation.

Leak-Free Seal: High quality OE style flange and band clamps are used for a complete 360-degree sealing surface eliminating leak paths.

Aggressive Sound: A straight through designed, free-flowing stainless steel muffler is used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque out of your rig.

Perfect Fit: 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.

Flow and Performance: MACH Force XP exhaust systems are constructed of 3" mandrel bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and improving throttle response.
