No, even my 1967 Barracuda had to do the emissions test. But if it fails miserably, I could just get QQ plates and then be emission exempt. But then NJ would limit the cars usage to just car shows and repair stations. NJ used to have a a triangle shaped inspection sticker that would do all inspection items except emissions, as long as you drove the car less than a certain mileage each year. I don't know if that program still exists since the only inspection item left is emissions.
