Description

Simple Installation:
All systems use factory mounting locations providing stability and hassle-free installation.

Leak-Free Seal:
High quality band clamps are included 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 409 stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT’s.

6" Diameter Polished Intercooled Tip:
Finishing off the exhaust is a 6" diameter, high luster polished, stainless steel slash cut tip with intercooling vents designed to reduce exhaust gas temperatures at the tailpipe. A unique stainless steel laser-cut powder-coated black aFe Power logo plate is riveted on for an aggressive style.
