Flow and Performance:
This Large Bore-HD exhaust system is 100% hand MIG-welded and constructed of 2-1/2'" mandrel-bent 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 that formed collectors are prone to produce.
Perfect Fit:
This system uses all factory mounting locations providing stability and hassle-free installation. 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.
4-1/2" Angle-Cut Rolled Edge Matte-Black Clamp-On Tips:
Finishing off the exhaust are dual 4-1/2" 304 stainless steel clamp-on tips with a matte-black finish. A unique laser-cut aFe Power logo plate is riveted on for an aggressive style.
Wheelbases:
Crew Cab/5'7" Bed (140" Wheelbases)
