    All-Round Exhaust Power. Standing up to everything the weather or road can throw at it with T-409 stainless construction, the aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Polished Tips is made to improve your 2014-2018 Sierra's sound and performance. Showing off a pair of large, brilliantly polished 4.5" exhaust tips decorated with the hard-charging aFe Power logo in black applique, this system speeds removal of exhaust from the system with a dual-out muffler and mandrel bent pipes. This generates up to a dyno-tested and proven +17 ft/lbs of torque and +14 horsepower across most of the RPM band, plus a larger, gruffer sound - a rumbling growl that gives your pickup a distinctive presence and that's free from droning or higher tones thanks to the system's absorptive muffler.

    Hardy Stainless Component. Made in the United States, the aFe Mach Force XP Cat-Back Exhaust is built out of 3" T-409 stainless steel tubing and a 21" muffler (single-in, double-out) made of the same metal. The tips are fabricated out of T-304 stainless to eliminate the risk of tarnishing. This part is engineered for an exact fit and bolt-on replacement installation using stock mounting locations, and is supplied with both a full hardware kit and a 2-year limited warranty.

    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 5.3L GMC Sierra's with the following cab and box configurations.
    • Crew Cab with the Short Box
    • Crew Cab with the Standard Box
