The aFe ATLAS 5-inch DPF-back exhaust system is built for 2011–2016 GM diesel trucks with the 6.6L LML V8. Constructed from mandrel-bent 5-inch aluminized steel tubing, it uses smooth transition bends to reduce turbulence, increasing flow and lowering EGTs. The system employs OE-style bayonet hangers, high-quality band clamps and factory mounting locations for a direct-fit installation, and it ships with all hardware and a two-year limited warranty.
