Gutted my DPF/DOC Last Night

A buddy and me gutted my spare DPF/DOC last night. After reading a bunch on here and other forums we used a rotohammer with an 18" bit and had both hollowed out within an hour.

One tip for anyone thinking about gutting a DPF, the rotohammer is the perfect tool, start by putting a hole all the way through the media (may have to go at it from both ends). Once you get a hole puched all the way through start breaking it out around the hole working from the center of the media outwards toward the case. The media will start to just chunk apart and fall through the open hole.

Just waiting for my tuner to show up with the mail man and we'll be ready to throw it all in

I just used a drill , hammer ,and chisel/ long screwdriver. But then I cut both ends off with a grinder and welded the shells onto my delete pipe. So now I have what appears to be a 4 inch factory DOC/DPF.

I used an air hammer and an 18" nut splitter (longest air hammer bit I could find, about $25), DOC took about 90 secounds and the DPF took maby 10 minutes. I know it looks like ceramic, but I used a mask, I dont even want to think about what could be in it. And yes punch a hole through the middle then work your way out.

My buddy has the pics on his iPhone. I'll get them tomorrow and throw them up. Looks like the mini maxx will be showing up tomorrow.

If you don't have access to bits that size. Just use a hammer drill with some concrete bits and a steel conduit. Drill all around the perimeter, then drill a bunch of holes through the center. Then use the conduit to punch bigger holes through the center until it starts to fall apart.

A mask is highly recommended.

No.
No.
Yes.

EDIT: The above answers are if all you did was hollow it out, not cut it apart and weld it back together onto a straight pipe.

I didn't take any pics (probably should take in-progress pics of my projects, but I never do). Hell, I don't even how how to upload a pic if I had one (hence no avatar). But to answer your questions, YES is was a Pain, and NO is doesn't looked "untocuched". It looks really good and no-one execept a person who knows exactly what a 6.4L DOC/DPF should look like will ever be able to tell the difference. But its a 4 inch pipe now, the welds are are machine made, the counter weight (or whatever that heavy can of nothing is) isn't there. The factory heat shields are still there and untouched. Looks really good and would fool me unless I laid down under the truck and really analized the minor details.
