[QUOTE="Powerman, post: 373147, member: 1611"] I wanted to hold onto the stock pipe, but couldn't find another at the time. I used a thin cutoff wheel to cut the holes like the picture, then there are little round tits on the cat that need to be drilled/ground out to get them to come out. Put the plates back on and TIG weld them. A plug and washer can be found at the auto parts store to plug the O2 sensor hole. I think it was maybe 18mm? [/QUOTE]
