AFE MACH Force-XP 3-Inch Dual Exhaust System with Black Tips; Side Exit (14-18 4.3L Sierra 1500)Find parts that fit my vehicle

Effective Exhaust. Getting into the thick of the action with +14 horses and +17 torque ft/lbs energizing your 2014-2018 GMC Sierra is as easy as bolting on the aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Black Tips. These dyno-tested and proven power gains come from the 29% boost to exhaust flow that the Mach Force XP generates. Removing the hot backup of fumes lets cold, fresh, oxygen-rich air into the engine, boosting power, throttle response, and even engine life (by cutting heat stress). Performance rises across the entire RPM band. This aFe Cat-Back looks great- with its aggressive black tips and polished, contrasting aFe logo - and creates a deep, belligerent exhaust note.

Reliable Stainless. Stainless steel is the material used for the 3” tubing, the straight-through high-flow muffler, and the black powder-coated 4.5" tips on the aFe Mach Force Cat-Back, to keep rust and corrosion at bay. The system bolts on with hand tools, with no cutting or welding required, and comes with stability generating bayonet hangers, hardware, and an extension tube for long bed variants. aFe warrants the exhaust system for 2 years, though its tough USA-made stainless build usually lasts much longer.

Application. The aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Black Tips is a system that fits the 2014-2018 GMC Sierras with the following cab and box configurations.
