It was off of my car. So what we did was that we took the connection between the header and the midpipe and unbolted that. Then we took the o2 sensor off, took off all the hangers and swapped his midpipe and muffler for mine. My exhaust was clamped on. I didn't feel like rewelding mine after I gave my exhaust to Rob. Anyways, all in all, after 1 battle scar, we got the exhaust swapped and it sounded great. I told him to come on by a week or so later so we can retighten those bolts and everything.Inder
