gutting a cat

Yes, if you have one after the cat. It won't effect the way the car performs, however because I think that O2 sensor is for emmissions.

the cat is for emittions, the o2 sensor is to determine lean/rich and adjusts the motor for such.
i have no idea if gutting the cat will effect the motor.

IN what year vehicle? OBD II (96-up) has pre and post HO2S and yes it will effect the O2 reading, it will be switching when it shuuoldnt be. If it only has a pre O2s, then it wont hurt.
OH, I thought he meant a real cat also, HAHA.

yes this is correct . and the second o2 is checking to see if the cat is doing its job correctly. so if its a 96-up dont mess with it.
i gutted my cat on the 88 truck i have and it was much more power. and fyi if its the big monster gm cats just pull the freaze plug thing out and fire it up and let all the crap come out. and put a new plug back in and go have fun.
if honey comb style big hammer and long rod or bar and have a big old time getting that stuff out. its kind of time consuming.
on our trucks it wont hurt it cuz they're pre-cat O2 sensors.

I can only speak for CA, I doubt itll pass with a gutted cat. I dont know how intense you alls "inspection" is, or what it entails. if I were you, i'd just leave it.

most cats only have a short pipe on either side were they tie into the exhaust. the easiest way would be to remove the converter and like said above, if its the honey comb style just go at it with a long pry bar (or something else thats just what i used) and hammer. kinda takes alittle time to get all the stuff out. we gutted the one on our shop truck 2000 s10 p/u and the engine light came on but it doesnt seem to run any different.
