    Improved Exhaust. Bolting an aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Polished Tips onto your 2014-2018 4.3L GMC Sierra is the same as bolting on +14 more horsepower and +17 ft/lbs of torque, gains proven by thorough aFe dyno tests. This exhaust system deploys mandrel-bent tubing and a high-flow muffler to generate both big power gains and a throaty, aggressive, boisterous exhaust note that will get your pickup noticed anywhere. Boosting exhaust removal by 29% and cooling the fumes by 100° F, the Mach Force eases backpressure so the engine breathes easier and throttle response improves - while looking great with its 4.5" polished tips badged with the aFe logo in black.

    Durable Construction. T-409 stainless steel is the material used for the aFe Mach Force Cat-Back's construction, including the 3" mandrel-bent pipes and the straight-through muffler. The tip is 4.5" T-304 stainless steel, a higher grade (aerospace quality) which is immune to discoloration over time. The part is designed for bolt-on installation, and comes with leak-preventing premium band clamps (creating a 360° seal), hardware, and bayonet tip hangers to provide steady mounting. It is warranted for 2 years and USA-made.

    Application. The aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Polished Tips is designed for use on 2014-2018 4.3L GMC Sierras with the following cab and box configurations.
    • Regular Cab with the Standard Box
    • Regular Cab with the Short Box
