I would be less concerned about emmisions legality if my town didn't do random inspection checkpoints. It's pretty impressive. They bring out a DMV truck with the emissions machine in it, block the road down to 1 lane in front of the police station, and flag cars into the parking lot. If you have a cammed up muscle car, you will be flagged in. Then they look under the car with mirrors, and put the sniffer in the tailpipe. If you look like you have a hooptie, they will jack up the front end and check the suspension for loose ball joints, etc.. If you do not pass, they will scrape your sticker and ticket you. Welcome to New Jersey. This is the reason I have a catted x.
