Ironically, none of the (at least the old SS unit and PP/FPS unit) are legal
either, even with cats since none were EPA/CARB approved. So while it may
pass the visual inspection, technically, it's still a modification to an
emissions control device (same as a tweecer, etc) with a non CARB approved
device.
I ran a catless pipe on my 92 (and old 89) at the track simply because
sustained high rpm on a lean(er) burn AF ratio is hard on the cats. I have
a PP pipe w/ cats for the street.
Whichever one you get, if you are looking for max performance dump the 2.25"
oulet and go to 2.5" or 2.75"
