      Excellent Cat-Back. Dressing up your 2014-2018 Sierra with a handsomely sinister pair of black ceramic coated 4.5" tips with gleaming aFe Power badges in polished stainless, the aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Black Tips is sturdy and fits well. This quality piece is all stainless steel for a long lifespan in all kinds of conditions. Mustering both constant-diameter pipes (mandrel bent) and a high flow muffler, the Mach Force XP develops a deep, loud growl with a lot of aggression in place of the factory exhaust note, while scavenging very efficiently, too. Relieving the backpressure of hot fumes gives more throttle response along with +5-10% horsepower and ft/lbs of torque.

      Fabricated for Performance. The aFe Mach Force XP is built to serious performance parameters, with precision fit and high quality 3" T-409 stainless steel piping. The tips are T-304 stainless. The muffler measures 21" and has a free-flowing single-in, dual-out blueprint. Covered by a 2-year manufacturer's warranty, this part is made for easy bolt-on application, and comes complete with OE-type bayonet hangers that won't shift or bend regardless of heat and 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 5.3L GMC Sierra's with the following cab and box configurations.
      • Crew Cab with the Short Box
      • Crew Cab with the Standard Box
