Great thread but i haven't seen any correct info. posted here yet, i'll start from the bottom and work up....

In Georgia, it is unlawful to raise or lower a vehicle more than 2 inches from the original manufacturers height.

When modifying your car, as long as all the parts are DOT approved then you are ok. i am checking on the sound ordinances for georgia now as soon as i can download the adobe reader...

The info. first posted in that forum regarding modifying exhaust was incorrect, that was the section and code applied to motorcycles in the state of florida, not vehicles, read on and you'll find someone else posted the correct information and the steps to testing the legality of it.

Supposedly he got out of the tickets also, interesting.
