The o2 sensor for the cats has NOTHING to do with the air/fuel ratio. There are o2s before the cats that do this.

You could get a CEL from removing the cats (and probably will). Ive checked with all the tuner manufacturers and none of them have an o2 delete. I dont believe there are spoofers out either. But, you could keep the o2 bung and try the anti-fouler trick. Get 2 spark plug anti-foulers, drill out one of them, screw them together, screw it into the o2 bung for the cat, then screw the o2 sensor into it. Works on quite a few cars (did on my old grand prix).
