2020-2022 Powerstroke 4" Downpipe Back Exhaust w/ Muffler (DDC-4F20M)

Note: Regular cab trucks WILL require modification.

Our 4" Downpipe Back Exhaust with Muffler replaces the restrictive factory exhaust on your 2020-2022 Ford Super Duty without going full straight-pipe. The full 4" mandrel-bent tubing holds its diameter through every bend so nothing chokes the flow, and the muffler keeps the tone strong but a little more civilized for daily driving. 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-4F20M
