Hey guys the month has finially come to get another inspection sticker for the MM. i recently just had a tune put on her and i wasnt sure if that would cause a big R for rejection. i was under the impression as long as the check engine light is off your all set, but people are telling me other wise now. any info. would be helpful. thanks

My MM just passed inspection in North Carolina.

They do a visual inspections to make sure your emissions system is intact. They check that there are no codes and it's at least 100 miles have been driven since the last codes were cleared.

I have a tune, completely new exhaust system, Big Thanks to Todd and Grand Muffler, with 2 hi-flow cats in place of the 4 stock cats.
