Description

The AFE 49-44035 MACH Force XP 5" Down-Pipe Back Race Exhaust System for your 2011-2015 GM 6.6L Duramax is a true 5" from the down-pipe back, the MACH Force XP exhaust is engineered to perform in the most extreme environments. This system is constructed from mandrel bent 5" stainless steel tubing for maximum flow, increased horsepower, increased torque and lower EGTs. The 2-piece tailpipe and bayonet style hangers provide a hassle-free installation. To provide a leak-free seal, OE style band clamps are used that offer a 360 sealing area. A 30" free-flowing straight-through designed muffler is used to produce a deep, powerful sound.

Installation is a Snap:
MACH Force XP exhaust systems utilize a 2-piece tailpipe design for a perfect fit by allowing adjustability at the tailpipe section. All systems use factory mounting locations providing stability and hassle-free installation.

Leak-Free Seal:
High quality OE style band clamps are used for a complete 360 sealing surface.

Aggressive Sound:
A free-flowing 30" long 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 mandrel bent 5" stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGTs.
