      Description

      Exhaust Power-Up. Creating a throttle that responds swiftly to your input, and beefing up the power of your 2014-2018 Sierra, the aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Black Tips is a bolt-on system focused on quality and results. This cat-back, sucking exhaust fumes out the tailpipe 29% swifter than the OEM exhaust, bleeds off backpressure so your GMC's engine reaches its potential, with +14 horsepower and +17 ft/lbs of torque gained. Lubricants also deteriorate more slowly with heat cut by 100° F. Topping off these benefits, the Mach Force adds a bold, macho exhaust note and looks great with its two black tips enlivened by laser-cut aFe badges.

      Aftermarket Excellence. aFe builds its Mach Force XP Cat-Back as a winner, using T-409 stainless throughout - which, though it will discolor, stubbornly defies rust and corrosion. The single-in dual-out muffler is a straight-through design, fully welded, while the 3-inch pipes feature mandrel bends. Supplied with bayonet hangers, 360° band clamps, and an extension pipe (for long bed/regular cab combos), this bolt-on part is easy to install. USA-made, it comes with a 2 year limited manufacturer's warranty.

      Application. The aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Black Tips is engineered to fit the 2014-2018 5.3L GMC Sierra's with the following cab and box configurations.
      • Regular Cab with the Standard Box
      • Regular Cab with the Short Box
