2013-2018 Cummins 4" SS Cat & DPF Delete - w/ Muffler (DDC-3D13M)

the muffler did not fit proper on one side and had to but cut and welded on the pipe side as well as wrong size clamps . may have to look into this fitting problem as I’ve done many of these kits and they usually fit nice .

With the stock OEM airbag system on my ram 2500 this exhaust system is what I needed for my application. The main concern was to give enough clearance for my air suspension. I only ran into on issue during the install, which was a bit annoying. I needed to add an 8 inch double make 4” pipe to make the female 4” on the muffler to the female connection on the stock oem tail pipe. Otherwise the exhaust sounds great, engine runs more efficiently.

The shop that did the install said if fit horribly and they had to spend a couple extra hours modifying it to make it work.
