Test pipes are direct flow through (less restriction/backpressure causes a gain in HP) and contain no catalytic converters. I know for FI systems the more open you make it the better... Therefore test pipes. BUT this is not technically legal and will in most cases of course fail you on any sniffer test.
As I see you are in Cali... I would suggest highflow cats as you will never pass emissions with test pipes. IMHO anyway.
Good luck with your decision.

If you want your Z to sound like zhit, get TPs
If you want your Z to smell like zhit, get TPs
If you don't like zhit, get HFCs.
Don't buy the HP zhit either. You going to feel the difference of less than 1% gain in HP? yeah right......

Dude, I am not sure what you are talking about. My testpipes gave me a +25hp difference. They might be loud, but when combined with the turbos, they are no louder then my old nismo exhaust. (at least until my wastegates open)

Fast Intentions resonated test pipes are good for 10 RWH and 12 lbs. of torque. This was on a bone stock 2006 350Z. I have the dyno charts to prove it...Tony (Oh and by the way, NO RASP at all)

ok, do the resonated test pipes smell? sorry for the n00b question, but ive searched a lot on this topic, but never heard of them smelling. is it that sulfur(rotten egg) smell? i think my cats are bad on my Z cause i already have that smell.
so if you cant figure out what the hell im asking in all that.haha. do the resonated test pipes give off a foul smell like im sure the regular ones do? thanks

There is a lot of work involved as well to make sure the testpipes are built to factory specs as to make sure they do not impose a bind on the system.

If I take a good dump before I go to the drag strip, I can accomplish the same results
