This is going to be tricky I'm afraid. Every of our 50 states has different emissions regulation and paperwork. In some cases emissions laws are even different by county. Ohio for example if you live in Medina county you need emissions check. But if you live 25 miles south it's exempt.

Typically they just put a sticker in the windshield and give a paper print out of the emissions test. Again every state is different and in some cases because these cars are getting older are exempt just because of age.

At least the USDM 2Gs came with a sticker similar to this under the hood. This is a '96:

I think that kind of sticker 19eclipse90 posted is enough for our officer's! Ill check it out if car has that sticker under bonnet. Otherways i'm going to have to find a place where to get new one.
Thanks folks!

Jnz Tuning is where I got that sticker from for my hood. Check with them if you need one.
