wow dude. just wow. put the o2 sensor in the new cat. there should be a bung for it on the exit side of the cat if not your gonna have to get one put on. a muffler shop will do it for relatively cheap

sounds like you got the wrong cat, pre OBD II had no bung for it, but OBD II's have a bung as part of the cat. was just looking at the 2 today

i just got a universal cat, not a specific cat, therefore there is no hole for the sensor

I'll bet any good muffler shop could drill a hole and weld the bung in. I doubt if it's that big a deal. But I hope you don't live in California. We have to have special cats which cost maybe $100 more than the other 49 states. Lucky us!

the bung basically looks like a bolt welded onto the muffler/piping any muffler shop should be able to do it quick and inexpensive.

This sounds really obvious, but I'll mention it anyway. Make sure that the location where the muffler shop installs the bung is within reach of the O2 sensor wiring. You don't want a strain on the wiring connector. You also want the bung at an angle that would make removing the sensor easy with a box or open end wrench (if you don't have the special O2 sensor socket - a deep socket with a slot to allow the wires to hang out).
