Installation is a Snap:
All systems use factory mounting locations providing stability and hassle-free installation.
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 race pipes are constructed of 4" mandrel bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT’s.
Warning: This free-flow race exhaust system requires the use of an aftermarket performance programmer with off-road tuning.
