gains from removing cats ?
(need some numbers)
will the car fail in the ispection if I did so?
will the simulators do the work and cheats the inspector?
thanks!
It depends on how they inspect. If they sniff, you'll fail. If they scan, you can pass by turning off the rear O2 DTCs and setting the codes as "enabled" but "x=off." If they scan only, you could still fail if they did a visual inspection and saw no cats.
Its not that complicated. If you remove cats you have to get sims for the rear O2 or get them tuned out. That way if they scan you are fine. But if you dont get sims you will fail the test for sure. If the do a sniffer test without cats you will fail for sure. Or if they do a visual inspection you will fail for sure.

Thanks guys.
You need to find a performance type of shop that does inspections. The shop I went to the owner has a 2002 ZO6, and the guys that work there are all into performance.
