Superior Exhaust. There's plenty of power hidden in your 2009-2013 5.3L GMC Sierra, imprisoned by the backpressure of accumulated exhaust fumes - and the aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Polished Tips is designed to uncage that beast and let your system breathe free. The Mach Force Cat-Back intensifies exhaust removal by 29% through its smooth mandrel bends and performance muffler, while deepening your Sierra's sound to a throaty, aggressive exhaust note. The throttle grows more responsive with backpressure eased, and your truck gains a dyno-tested +17 ft/lbs of torque and +14 horsepower - along with the savage styling of black-badged 4.5" polished tips.

Heavy-Duty System. Built to last, the aFe Mach Force Cat-Back incorporates T-304 stainless steel for the tip and T-409 stainless for the muffler and 3-inch mandrel-bent tubing, both nearly rust-proof grades. An extension tube for long bed variants is included, along with the hardware, 360° band clamps, and bayonet hangers needed for bolt-on installation. The part is manufactured in the United States and comes with a 2 year limited warranty from aFe.
