      Gain Power. A pulse-quickening roar of exhaust sound and a strong jump in power and performance are the hallmarks of the aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Black Tips, a high-quality USA-made upgrade to your 2009-2013 4.3L Sierra. Sending the exhaust fumes streaking out around free-flowing mandrel bends and through a single-in dual-out muffler, the Mach Force boosts exhaust flow by 29% and cools the gases by 100° F. In practical terms, this puts at extra +14 horsepower and +17 ft/lbs of torque at your beck and call, while improving throttle response. The part also adds some fierce styling to your Sierra with silver aFe badges on the black tips.

      Sturdy American Quality. Manufactured in America, the aFe Mach Force Cat-Back is fabricated from stainless steel throughout, including the 3" mandrel-bent tubing and the straight-through muffler. The tips measure 4.5" and are black powder-coated with a polished stainless badge. This part, protected by a 2 year limited warranty, is built for bolt-on fitment, using OE-style bayonet hangers which keep the system stable even in the heat and vibration of a working truck.

      Application. The aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Black Tips is built to fit the 2009-2013 4.3L GMC Sierras with the following cab and box configurations.
      • Regular Cab with the Standard Box
      • Regular Cab with the Short Box
