Simple Installation
This system uses factory mounting locations providing stability and hassle-free installation.

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 3-1/2" mandrel-bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT’s.

5" Diameter Polished Intercooled Tip
Finishing off the exhaust is a 5" diameter, polished, stainless steel slash cut tip with intercooling vents designed to reduce exhaust gas temperatures at the tailpipe. A unique stainless steel laser-cut aFe Power logo plate is riveted on for an aggressive style.
