The aFe 49-43122 is a dual 4 inch DPF-back exhaust for 2015-2016 Ford Super Duty trucks with the 6.7L Powerstroke. A mitered merge collector splits flow to two tailpipes that exit on each side ahead of the rear tires.

It is built from 4 inch mandrel-bent 409 stainless steel and finished with dual 6 inch clamp-on tips in polished or black. Intercooling tailpipes help lower exhaust gas temperatures at the tips.

• 4 Inch 409 Stainless Steel: Mandrel-bent tubing for smooth flow.
• Mitered Merge Collector: Reduces turbulence where the flow splits.
• Intercooling Tailpipes: Help cut exhaust gas temperatures at the tailpipe.
• Dual 6 Inch Tips: Clamp-on tips in polished or black.
• Factory Mounting: Uses OE-style bayonet hangers and factory mounting points.
