The aFe Large Bore-HD 4" dual DPF-back exhaust for 2016 GM Diesel Trucks with the 6.6L V8 (LML) converts the stock single exhaust to an aggressive dual layout using 4" mandrel-bent 409 stainless tubing. It employs OE-style bayonet hangers, a bolt-on bracket supporting the driver-side tailpipe and fits without moving the spare. Dual 6" polished tips and laser-cut aFe badges finish the installation.
