yet another y pipe question
Ok guys i got a cali emissions 99 sel and previous owner somehow got a cattman fed emission y pipe on it, my question is now if i run the o2s to the rear of the cat will that eliminate my codes? i dont even see a precat on the front manifold....its not really making much sense to me right now and i only see 1 o2 on the car, unless the others are tucked away elsewhere that i cannot see.. but basically if i got cali emissions and a fed y pipe where would i have to put the o2s to eliminate the codes??

I am unsure of the amount of codes you have but from what I see on courtesy site for the y-pipe for a '99, you have 4 oxygen sensors. You may want to take a look at the link:

Yea ive looked at that... i know i got 4 o2s although as of now theres only 2 on my car... i found the two plugs in front if the manifold that are missing right now... looks like im going to have to replace them and run extensions behind the cat and weld in a few bungs
