You mean like the MBRP downpipe-to-flange replacement front pipe that has no DOC on it? Pretty common item.

MBRP makes one, but if you are connecting it to your Magnaflow 4" kit, you will have to cut off the 3.5" adapter on the Magnaflow pipe. The MBRP front-pipe (cat delete) is 4".

Im not really sure about my Magnaflow system on the truck. It came with it and has been cut up (shortened in the rear)

If you could design a system from the turbo back what would you do?

Diesel Oxygenation Cannister.

MBRP S6004409, turbo-back system. Same as I put on my truck.

I was trying to hint that diesels don't have catalytic converters. They have DOCs.

S6004409 is an MBRP part number for a full (no cat) exhaust system.
