2017-2019 Chevrolet Silverado 3500 HD - 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 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.
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).
Emissions Disclaimer: This product does not require a CARB EO#
All aFe exhaust systems are engineered and manufactured in our Corona, California facility.
