The aFe Large Bore HD 49-13028 is a 4 inch DPF-back exhaust for 2011-2014 Ford Super Duty trucks with the 6.7L Powerstroke. It replaces the factory exhaust behind the diesel particulate filter with larger, smoother tubing.

It is built from 4 inch mandrel-bent 409 stainless steel and finished with a polished 5 inch double wall tip. OE-style band clamps and bayonet hangers make for a clean, simple install.
