aFe introduces the MACH Force XP exhaust system for the 2014-2015 GM Silverado/Sierra 1500 V8-5.3L with the 143.5" and 153" wheelbases. This cat-back is constructed using 3" mandrel-bent 409 stainless steel and uses a free-flowing muffler. OE-style bayonet hangers and band clamps provide a stable pipe location during high vibration and heat conditions. The smooth curves and increased diameter of the exhaust system helps remove horsepower robbing restriction and keeps exhaust gas flowing smoothly for increased horsepower and torque. The system is finished off with a black powder-coated 304 stainless steel, rolled slash-cut tip for an aggressive style.

Installation is a Snap:

This MACH Force XP uses all factory mounting locations providing stability and a hassle-free installation.

Leak-Free Seal:

High quality OE-style flange and band clamps are used for a complete 360-degree sealing surface eliminating leak paths.

Aggressive Sound:

A straight-through designed, free-flowing stainless steel muffler is used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque out of your rig.

Perfect Fit:

OE-style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. The bayonet tip holds the hanger bushing in place for an OE-style fit that does not change with time.

Flow and Performance:

MACH Force XP exhaust systems are constructed of 3" mandrel-bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and improving throttle response.
