aFe ATLAS 4 IN Aluminized Steel DPF-Back Exhaust System w/Polished Tip GM Diesel Trucks 17-18 V8-6.6L (td) L5P - 49-04085-P

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 Mach FORCE-Xp exhaust system is constructed of 4" mandrel-bent aluminized tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT's. Polished Tips: Finishing off the exhaust are dual high luster, polished 304 stainless steel slash-cut tips. This tip features a laser-cut stainless steel aFe power badge for an aggressive style.
