if it wouldnt pass emissions, what would be the point of selling performance cats be in the first place instead of just replacing it with a straight pipe?

Because under a visual roadside inspection its illegal if you are missing your cat. And highperformance cats are generic meaning on certain cars with less strict emmission standards they may pass fine where as when you install them on another car it may fail.

I know that they have the 4-Wire o2, but I always thought there was another one?

because when I went to look for an o2 for my car he said that there were 2 different ones, one for the front and one for the back or whatever... and the one for the front was a lot cheaper...anyways still looking for one dont' want to buy an expensive one, not keep this engine for long
