2020-2022 Powerstroke 4" Downpipe Back Exhaust No Muffler (DDC-4F20)

Note: Regular cab trucks WILL require modification.

Our 4" Downpipe Back Exhaust replaces the restrictive factory exhaust on your 2020-2022 Ford Super Duty. It's a no-muffler setup, so you get the deep, aggressive tone the 6.7L is meant to make, and the full 4" mandrel-bent tubing holds that diameter through every bend so nothing chokes the flow. The tubing is aluminized steel, the hangers are contour bent and welded on before it ships, and the flanges are heavier-duty than stock. Clamps are in the box and it mounts to the OE hanger locations, so it bolts up without a fight. 

Part Number: DDC-4F20
