GOD I am glad I live in a non emissions county in Texas! I would be a clock tower sniper if I had to put up with all that crap! In my opinion the only thing that should matter is what comes out of the tailpipe! Back when I worked for Hyundai one of the tech people told me that on a dirty day in LA that the exhaust coming out of the car was actually cleaner than the air going in! That's what you get for living in a HOLE!
