      More Power. Hitting the road in style, the aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Black Tips puts a pair of savagely handsome black tips with polished logos on your 2009-2013 Sierra, while cranking out superior performance too. The system yields +14 horsepower and +17 torque ft/lbs - both dyno-proven - by sweeping away fume backpressure so the engine breathes deeper. The single-in, dual-out muffler also gives your machine a commandingly aggressive "voice" that sets it apart as a leader, not a follower.

      Lasting Part. Though warranted for 2 years, the T-409 stainless steel used for the aFe Mach Force Cat-Back's 3-inch tubing and high-flow muffler usually lasts far longer. The 4.5" tip is also stainless, finished with black powder-coating, with a polished stainless badge riveted on for permanent style. Premium band clamps furnish a 360° seal against leaks, while OE-type bayonet hangers keep the system solidly in place. This precision fit, bolt-on cat-back system is 100% USA-made.

      Application. The aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Black Tips is designed to fit the 2009-2013 5.3L GMC Sierra's with the following cab and box configurations.
      • Regular Cab with the Standard Box
      • Regular Cab with the Short Box
