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

The small section of pipe with a bend did not have a flare on it to fit over the outlet of the muffler. Simple mistake but irritating at time of install

Awesome as always

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 .
