if i use my Diablo to turn my O2 sensors off since i have an x-pipe, when they plug their computer to my cars computer 2002 Mustang GT will it pass or fail?

What state do you live in? I think some states still do the smog test regardless of 96+ or not and if they do you will fail. I think PA still will hook the sniffer up but i'm not positive.

Maryland, they just do the computer hook up on 96 plus. . .

Thats what i thought until a guy from pep boys told me otherwise. Maybe he was new... Anyway you'll pass with just a hook up no problem. But most likely they will hear your exhaust, want to check it out, see the new pipe with no cats, and possibly fail you.
