But from what I've been seeing is around the country they are doing OBDII tests only on 1996 and newer cars. Some places if it fails the OBDII test they will tail pipe test it but in Illinois your only option on a 96 and newer car is OBDII test you fail that and you have to fix it till there are no stored codes. Even if the code is something stupid like a tranny code which has no effect on emissions output.
It all depends on the state. Some states testing machines cannot read the JDM ECU. When I was in RI their machines were able to read my ecu and it was fine. When I moved to CT the testing machines could not read my ECU at all. So they did a sniffer. I passed the sniffer test catless(just barely iwas like 217/220, only 3 points from failing). If you can do a tailpipe test it will actually be easier for you to pass than an OBDII test.
