I have recently purchased a 2001 SS.
It is from out of state, and I want to know what the state emission
requirements are here in Arizona.
Do they do sniffer test here, or just visual inspection and plug-in
to the obd plug and check for codes?
i recently passed last month with no cats, no EGR, no AIR, and no rear o2's.
i DID get SES codes however, but you have to go to a tuner and have them tune them out, or set the perameters so low that it wont trip the code. the local guy i went to, NicD (tech username) who does great dyno tuning/minor tuning, deleted mine at a real good price with LS1 edit.
i just passed emissions last month, i did the same thing as the guy above me did. I passed with no cats, o2 sensors or egr valves. i went to NicD to get my SES light turned off. They did pop my hood, i'm sure they saw that it didnt have an egr LT's etc., but i still passed. took about 5 minutes
