# aFe LARGE BORE HD 5in 409-SS DPF-Back Exhaust w/Black Tip 2017 GM Duramax V8-6.6L (td) L5P

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 EGT's. 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.
