Um they look for alot of things like working lights/signals, seatbelts, things like that. Most places wont care as long as your care is safe (good tire tread left, brakes are within spec). The emmisions is done on a dyno type thing yes. As far as that, there are certain numbers you must do better then or no go. Collegeville isnt too far away from where my friend works (Chalfont) im sure hed hook you up.. Most people who are mechanics are obviously car people. and with that said, they are willing to look the other way on some things. Whats your full setup like???
