i just moved up to nh and i was wondering what the emissions laws were here. i am hoping that they are better than mass. do they do dyno emissions testing or just visual? i just want to see what i can get away with :)

Some shops still give them the basic tailpipe test, but many don't.

Many AWD cars now have stickers under the hood to explain that putting an AWD car on a 2wd dyno is going to lead to a broken garage.
