Need some advice on gutting used DPF/DOC

[Phrogcrew]

I have aquired a used DPF/DOC and plan to gut them to make a stealth delete pipe. My quesstion is do I take everything out, or do I just make a hole and leave some of the stuff in there? If anyone has gutted one and has some pointers, I would greatly appreciate it.

I've never gutted a dpf, but have killed many cats in my lifetime...

Through pipe it.. its the easiest most clean way to do it and not create obstructions. Well, other than the diameter of the pipe, that is..

Did a search and came up with these for ya:

Finally done it

The Links were a great read, but not definitive as to how much media to take out of the DPF/DOC. Remove all media or just punch a hole. Anyone else have any insight as to which way to go.

Just punch a hole and run a straight piece of pipe through it. Problem solved.

I gutted mine entirely. I hear people saying if you remove all of the media it will sound hollow but if you don't remove the media it will collect and build up = resulting in high exhaust temps and other issues. If I had to do this "hollowing out project" I would have drilled a 3 or 4" hole and ran a pipe thru it but then i figured it would be a pain inserting a pipe into the dpf and turbo back exhaust. Oh well, completely hollowed out worked for me.

Does the DPF/CAT sound hollow now that you gutted it? If you knock on it does it still sound solid?

It's easiest to just gut the whole thing. Use some hole saws or large dill bits.

As far as the sensors go, can you leave them hooked up, or do they need to be disconnected? I have heard both but would like to hear from some one with experience.

I had to leave mine hooked up because SCT livewire will stay in high idle if a sensor is bad or disconnected
