Large Bore-HD 5 IN 409 Stainless Steel DPF-Back Exhaust System

Simple Installation:
All systems use factory mounting locations providing stability and hassle-free installation.

Leak-Free Seal:
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.

Wheelbases:
Crew Cab/Short Bed, 6.6ft Bed, 153.7" Wheelbase
Crew Cab/Long Bed, 8ft Bed, 167.7" Wheelbase

Note:
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).
