I don't see a problem with deleting the cat, shouldn't throw a CEL but the only thing its going to do is probably make your car annoyingly louder. I deleted my catalytic converter on my RX7 and its obnoxiously loud.

Wankels are notoriously loud anyway. I have a friend that had a 2nd gen RX7 (I want to say ~'89) and it was pretty loud. Granted, it had a rebuilt engine and probably not much in the way of emissions control, but it was loud. I doubt removing the 2nd cat on one of our cars would really add that much extra noise, since you've still got a resonator and the muffler after it, plus a couple of bends. What it *will* do is make it more likely that you won't pass emissions (if required) and it might affect your 2nd 02 sensor readings.
