A word of caution.

Do not put a replacement O2 sensor into the cat that a bad(broken) O2 sensor was removed from.

You'll end up with two broken O2 sensors if you do.
Sorry, didn't mean to suggest that.

If the code is on, he's likely needing a replacement sensor whether he replaces the cat or gets a test pipe.

I just destroyed the second cat this year. The first one blew apart and crushed the O2 sensor. I haven't gotten this one off the car yet, but I definitely hear the death rattle again. I didn't notice a drop in power with this one, but I did notice a little with the last one. As far as I know, there was no damage caused by the cats failing.

That's not necessarily true. Oxygen sensors do go bad without being destroyed by the catalytic converter. On my Miata, I changed the oxygen sensors and they did not fail afterwards. I would agree that if you know you have a bad converter, you should hold off on replacing the oxygen sensor until you replace the converter.
