The aFe POWER ATLAS DPF-Back Exhaust System (part number 49-04041-B) is engineered as a direct-fit upgrade for the 2011-2013 GM 6.6L Duramax.
Interested in a new exhaust system? Check out the ATLAS DPF-Back exhaust system by aFe. This system is constructed from 5 in. mandrel-bent aluminized steel tubing. Smooth transition bends allow for low turbulence, increasing horsepower, toque and lowering EGTs. 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 7 in. wrinkle-black powder-coated tip with a laser-cut stainless steel aFe power badge. Tip features a drain port on the bottom to keep rust and corrosion away. ATLAS exhaust systems are the perfect combination of performance, fit and value. High quality OE-style flange and band clamps are used for a complete 360 degree sealing surface. All aFe systems are engineered and manufactured in our Corona, California manufacturing facility.
