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

Aggressive Sound:
A muffler delete-pipe is used for a true race-inspired sound and maximum flow.

OE 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 4" mandrel bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT’s.

6" Polished Tip:
Finishing off the exhaust is a high luster, polished 304 stainless steel slash cut tip with intercooling vents designed to reduce exhaust gas temperatures at the tailpipe. This tip also features a drain port on the bottom to keep rust and corrosion away.
