AFE MACH Force-XP 3-Inch Dual Exhaust System with Polished Tips; Side Exit

High-Flow Action. The aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Polished Tips is a liberating solution to the problem of how to let your 2014-2018 5.3L Sierra's engine achieve its unrealized, latent capabilities. Eliminating the restrictions of the factory exhaust, the Mach Force XP sends exhaust streaming out 29% faster, letting more cold air flow into the engine for a hefty boost of +14 hp and +17 ft/lbs of torque (dyno proven). The free flow is tuned to create a strong, vigorous exhaust noise, and the system ends in a pair of 4.5" tips polished to a mirror brilliance and finished off with high quality black laser-cut aFe badges for a competitive, combative feel.

Stainless Steel Build. aFe's engineers use stainless steel for the entire structure of the Mach Force XP Cat-Back Exhaust, with most of it made from T-409 stainless and the tip from aerospace grade T-304 (with a black-coated laser-cut stainless badge riveted on). USA-made, both the intermediate pipes and tailpipes are 3" in diameter and mandrel bent. This system comes with band clamps, bayonet hangers, and hardware, and can be bolted on easily to the factory mounting points without welding or drilling.

Application. This version of the aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Polished Tips is designed to fit the 2014-2018 5.3L GMC Sierra's with the following cab and box configurations.
