      Professional Cat-Back. Crisp, ultramodern, and aggressive, the aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Polished Tips promises hard-charging power with its gleaming exhaust tips bearing the aFe badge in black. The Mach Force lives up amply to that promise, amping up the engine with dyno-tested +17 torque ft/lbs and +14 horsepower across the whole RPM power band. The smooth flow created by turbulence free mandrel bends and a wide-open muffler expels exhaust 29% more efficiently, relieving backpressure for better performance and throttle response. The aFe XP Cat-Back's exhaust note is commandingly aggressive, leaving no doubt your 2009-2013 Sierra is boss.

      Rust-Resistant Design. The aFe Mach Force Cat-Back is a bolt-on component, designed to be attached with hand tools using bayonet-tip hangers that keep the system positioned exactly despite years of vibrations. USA-made and warranted for 2 years, this cat-back is fabricated out of 3" T-409 stainless steel tubing, with mandrel bends throughout. The muffler and tips are also stainless - the tips are made from T-304 stainless and feature a black-coated laser-cut aFe badge.

      Application. The aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Polished Tips is designed to be used on the 2009-2013 4.3L GMC Sierra's with the following cab and box configurations.
      • Regular Cab with the Standard Box
      • Regular Cab with the Short Box
