aFe Large Bore-HD 4 IN 409 Stainless Steel DPF-Back Exhaust System w/Polished Tip

Flow and Performance: This Large Bore-HD exhaust system is 100% hand MIG-welded and Constructed from 4" 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. Perfect Fit: This 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 sh eet for Cab configuration for further details. 5" Angle-Cut Rolled Edge Polished Intercooled Clamp-On Tips: Finishing off the exhaust are dual side exit 5" stainless steel intercooled clamp-on tips with a polished finish. A unique laser-cut aFe Power logo black powder-coated plate is riveted on for an aggressive style.
