I live in Chattanooga, and I hear the new emissions testing TN started about 6 months ago is pretty weak. They just check for your check engine light to make sure it's not on. They check under your car to see if you have a catalytic converter, and then they check the pressure in your fuel tank. I heard they don't even pop the hood or hook anything up to the exhaust pipe. However I haven't gone yet, so I can't verify. I'm curious, when I start building my turbo motor, I want to leave all the crap off of it that I don't need that gets in the way and makes it a pain to get to the spark plugs. Does anyone in this area know if that will have any negative repercussions? I don't want to build this motor, and then have to add crap back onto it a few months down the road.
