they hook it up via the obd port, no sniffer test. As long as you dont have any codes come up your fine. if you do have codes come up, either throw the o2 sims on there, or get them tuned out. its the rear o2s that will give you trouble. also, erasing the code wont work, because that makes your computer not ready for emissions testing and you'll fail the test.
btw, ive got an 01z with headers, hi-flo cats and my rear o2s have been tuned out from my tune and i passed emissions with no issues.

if your not throwing codes, then your fine. All they do is hook it up to the obd port like i said and just to a scan to see that all systems are normal. They just roll past the dyno and hook up the comp and min later your off on your way home. They dont even test the fuel caps anymore.
