Richard, a couple years ago when I went in to get the u-bend taken out, the guy was saying that I should replace the cat. Something about the amount of heat that was coming off of it can show that one is clogged or something that the guy at the muffler shop said. I do not know if it is true or not, but you can kinda of smell a different smell from the car from time to time!

Fiin, I think I will try it without it and see what happens and maybe I will get lucky but if I have to have it, then I guess I will get one cause I do not know anybody with a scanner to shut it off. If I do have to get a o2 dummy thing though, who has the best price on them?

I have one more question. If I buy the bolt up 3" downpipe from zzp, am I going to have to have the end welded on or anything welded on or will it be a direct replacement and bolt up to the manifold and back section of the exhaust system. I just did not know since it is 3" and the stock system is 2.5"

It will bolt right in. The downpipes from ZZP have a reducer section that is 3" where it bolts to the exhaust manifold, but it reduces to 2.5" in order to match the catback. you should be good
