      Enhanced Cat-Back. Sizzling power gains and an aesthetic boost are what you can expect after installing the aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Polished Tips on your 2009-2013 Sierra, with the high-flow system draining off exhaust backpressure fast. The 29% exhaust flow boost clears fumes and strengthens the front-to-back draft through the system, infusing the engine with cold, dense air for +14 horsepower, +17 torque ft/lbs, and a noticeable jump in throttle response. Aggressive styling is added by the flaring 4.5-inch mirror tips, with their black applique aFe badges, while the exhaust note strengthens to a powerful, fierce roar when you stamp on the gas.

      Sturdy Component. Manufactured in the USA, the aFe Mach Force XP Cat-Back is made to be installed with hand-tools, bolting onto the factory mounting locations using the supplied hardware. The part is made mostly from T-409 stainless steel, which is almost totally rust-resistant but will discolor over time; the polished tip is T-304 stainless, which never dims. This cat-back uses 3-inch mandrel-bent tubing throughout plus a welded straight-through muffler. It is covered by a 2-year manufacturer's warranty.

      Application. This aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Polished Tips is made to fit the 2009-2013 4.8L GMC Sierra's with the following cab and box configurations.
      • Regular Cab with the Standard Box
      • Regular Cab with the Short Box
