Pretty much anything that doesn't affect the OBDII system should be fine. They don't actually test what's coming out of the tailpipe(s) - unlike states such as California or Colorado. That means that, as long as all of the OBDII components are in place, you pass.
thanks for the reply. so it's open season except for test pipes, eh? what about you guys with test pipes? are you worried about emissions testing at all? also, which mods hurt the _street_ drivability of the z? i believe the z is a very easy and forgiving car to drive. it's my daily driver and i would hate it if mods make it hard to drive to z. thanks again.

You might get lucky and pass the headers inspection on your Z's as its a bit tight (space-wise) so they might not see them. I can barely seem mine on my G coupe. In any case, I hope I pass emissions as I live in California. Anyone know the consequences of not passing emissions? I understand your car won't get its proper registration and such but will you be fined or anything for improper pollution?

Just don't put in Headers and Test Pipes and you should be fine. If you do choose to put in test pipes because of the big hp gains then it will only take you about 30 minutes to swap the cats back in before the test.

Ok, when I said "states like Colorado and California", I was giving examples. Don't take my word on what is checked in your state - look on your state's Department of Motor Vehicles website. In Texas, I have not seen a vehicle visually inspected during emissions testing or seen a tailpipe sniffer used. All I have seen is OBDII tests in Texas.
In California, if something beside a cat-back exhaust is on your car, and you don't have a CARB EO number for it, then you most likely will not pass visual inspection. If something is REALLY out of sight, you may pass if it doesn't affect the sniffer test.
You will not pass with a Supercharger unless it is CARB certified (and has an EO - Executive Order - number).
