High quality band clamps are included for a complete 360-degree sealing surface.
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 5" mandrel-bent 409 stainless-steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGTs.
6" Diameter Polished Intercooled Tip:
Finishing off the exhaust is a 6" diameter, high luster polished, stainless-steel slash cut tip with intercooling vents designed to reduce exhaust gas temperatures at the tailpipe. A unique stainless steel laser-cut powder-coated black aFe POWER logo plate is riveted on for an aggressive style.

Cutting the stock exhaust behind the DPF (Diesel Particulate Filter) is required for all cab configurations. (see instruction sheet for cut locations listed on all wheelbases applicable).
