    Strong Performance Gains. Putting some zing into your 2009-2013 GMC Sierra's performance, the aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Black Tips hustles hot exhaust fumes out the tailpipe 29% faster than stock, cutting the temperature by up to 100° F. Freeing up the system from backpressure, the Mach Force XP lets loose a deep-throated roar through its high-flow muffler and mandrel-bent pipes - a powerful statement backed up by dyno-tested +14 hp and +17 ft/lbs of torque strength gains. The system also increases the throttle's responsiveness and slows lubricant deterioration in the engine – as well as looking like a million bucks with its dramatic silver aFe logo on black tips.

    Manufactured for Sturdiness. Built rugged, the aFe Mach Force Cat-Back is made for easy direct fit installation, attaching to factory mounting points without drilling or welding. All hardware, bayonet hangers, clamps, and a long bed extension tube are included. The smoothly flowing mandrel bends are made in 3" T-409 stainless steel piping, while the muffler is also welded stainless. The band clamps provide a 360° leak-proof seal. This system comes with a 2 year limited warranty.

    Application. The aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Black Tips is designed to fit the 2009-2013 4.8L GMC Sierras with the following cab and box configurations.
    • Regular Cab with the Standard Box
