aFe Large Bore-HD 4 IN 409 Stainless Steel DPF-Back Exhaust System w/Polished Tip - Chevy/GMC 2017-2019 6.6L

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 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.
