The bayonet tip holds the hanger bushing in place for an OE-style fit that does not change with time. Flow and Performance This exhaust system is 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. 5" Diameter Polished Intercooled Tips: Finishing off the exhaust are 5" diameter, polished, stainless steel straight cut tips 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. **Cutting stock exhaust is required.
