Simple Installation:

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

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:
This Large Bore-HD exhaust system is constructed of 5" mandrel-bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT's.

Polished Tip:
Finishing off the exhaust is a high luster, polished 304 stainless steel slash cut exhaust tip. This tip features a drain port on the bottom to keep rust and corrosion away.
