    Big, Aggressive Sound. The aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Polished Tips represents a one-stop upgrade for your 2014-2018 GMC Sierra, improving sound, performance, and appearance in one slick package. This stainless steel system creates a powerful, aggressive exhaust note that sinks to a rumbling growl when cruising but bursts out in a roar when accelerating. The Mach Force XP adds +14 horsepower and +17 ft/lbs of torque to your machine by clearing away exhaust vapors before they can back up into the engine. The two 4.5-inch mirror polished tips display the aFe Power badge in black for high-performance styling.

    Built for Years of Use. Featuring stainless steel construction throughout, the USA-made aFe Mach Force XP Cat-Back has 3" pipes and a 21" muffler made from T-409 stainless steel, plus a pair of T-304 stainless steel exhaust tips. Though warranted for 2 years, this nearly rust-proof system usually lasts much longer. Bolt-on installation as a direct fit replacement part using the factory mounting locations is helped along by included hardware, band clamps, and bayonet hangers.

    Application. This aFe Mach Force-Xp 3 in. Split Side Exit Cat-Back Exhaust with Polished Tips is designed to be used on the 2014-2018 4.3L GMC Sierra's with the following cab and box configurations.
    • Crew Cab with the Short Box
