Simple Installation:
All systems use factory mounting locations providing stability and hassle-free 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.
Massive 7" Black Tip:
Finishing off the exhaust is a powder-coated black 304 stainless steel exhaust tip. This tip features a drain port on the bottom to keep rust and corrosion away. A unique stainless steel laser-cut aFe Power logo plate is riveted on for an aggressive style.
