In NC they simply perform a Safety Check for 1995MY and earlier vehicles. They will check for holes in exhaust, etc...but there is no OBD check or tailpipe apparatus used to measure emissions for '95 and older cars. Some inspection stays will perform a visual/tamper inspection as part of the Safety inspection as the car will be lifted about 1 foot and the hood will be opened. Based on what you have described I think you may be ok. Here is a good site for reference. http://www.ncdot.org/dmv/vehicle/registration/inspection/
