Interested in a new exhaust system for your LML Duramax? Check out the ATLAS DPF-Back exhaust system by aFe. This system is constructed from 5" mandrel-bent aluminized steel tubing and uses high quality band clamps and OE-style bayonet hangers. This unit uses all factory mounting locations to provide a quick, hassle-free installation. Also included in this exhaust system is a massive 6" diameter, polished 304 stainless steel tip with a laser-cut stainless steel aFe power badge. ATLAS exhaust systems are the perfect combination of performance, fit and value.
All systems use factory mounting locations providing stability and hassle-free installation.
High quality band clamps are included for a complete 360 degree sealing surface.
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 ATLAS exhaust system is constructed of 5" mandrel-bent aluminized steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT’s.
