Hollowing out CAT/DPF

Wondering if anyone has hollowed out their CAT and DPF instead of using a delete pipe?

If yes, do you have any advice for someone who wants to try it?

What did you use?

I did it on my 03. I just used a piece of steel rod and a hammer. It's pretty slow going at first, just making puncture holes. You'll think you arent getting anywhere, but after several of those, that mess starts to break up pretty easily.

Its not real cost effective to do this, they are very spendy to replace if you need to. Why not just get a kit to replace them instead?

What Nate said I agree,

Thought it would be good to have the look of stock so if Barney started looking into it, he might not catch on.

If warrantee is out, I don't see why you'd replace it unless Big Brother gets involved. We don't have inspections yet here where I live.

P.S. How many miles does warranty cover?

I bought a used dpf for 400 and hollowed it out. I used a hammer drill and a long one inch bit. Wear a mask, it is dusty and has some kind on insulation in there too.

I just did this too for the same reason . Bought a used one and used an air hammer with a long chisel in it . It went pretty quick,but def. wear a mask. The cat was easy ,the dpf was a little tougher but not bad.
