      Quality and Strength. Letting the exhaust gases flow out without hindrance through mandrel-bent tubing and a single-in, dual-out muffler, the aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Black Tips celebrates the increased power it gives your 2014-2018 Sierra with a powerful, aggressive exhaust note. The house dyno at aFe indicates +14 horsepower and +17 ft/lbs of torque gained above stock with the Mach Force XP installed. Made from durable T-409 stainless, this system also upgrades your truck's looks, with a pair of stealthy, handsome 4.5" black ceramic coated tips, proudly bearing the aFe Power badge in contrasting polished stainless.

      Rust-Defying Stainless. The aFe Mach Force XP is fabricated from T-409 stainless steel throughout, a medium grade that shrugs off rust and corrosion but may tarnish. The tips are T-304 stainless under their ceramic coating. The high-flow 21" muffler is designed to absorb and eliminate higher pitched noises for a better exhaust tone. Bolt-on and warranted for 2 years, this cat-back attaches via bayonet style hangers that keep pipe position stable over time regardless of vibrations.

      Application. This aFe Mach Force-Xp 3 in. Split Side Exit Cat-Back Exhaust with Black Tips is designed to be used on the 2014-2018 4.3L GMC Sierra's with the following cab and box configurations.
      • Crew Cab with the Short Box
      • Crew Cab with the Standard Box
