Flow and PerformanceThis Large Bore-HD exhaust system is 100% hand MIG-welded and Constructed from 5" mandrel-bent 409 stainless steel tubing for maximum flow. The smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT's. A mitered merge collector is also incorporated to eliminate dead space that can cause turbulence and hinder flow. Some cutting is required.

Perfect FitThis system uses all factory mounting locations providing stability. Includes OE-style bayonet hangers which 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. Some cutting maybe required during install. Please see instruction sheet for Cab configuration for further details.

6" Diameter Black Intercooled Tip: Finishing off the exhaust is a 6" diameter, black, 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.
