The aFe Large Bore-HD 49-43090 is a 5 inch 409 stainless steel DPF-back exhaust for 2017-2026 Ford F-250 and F-350 Super Duty trucks with the 6.7L Powerstroke. It replaces the factory pipe behind the diesel particulate filter and keeps all emissions equipment in place.

The system uses mandrel-bent stainless tubing, a 5 inch band clamp at each joint and a hanger clamp on the over-axle pipe. It is available with a polished or black tip.

Re-tighten the clamps after the first 50-100 miles.
