Rusted tight O2 sensor

I assume you mean a can of PB Blaster. This is a rinse and repeat process. Soak it let it sit for a couple hours. Try it again, and if it doesn't work give it some taps with a hammer to try and break up the corrosion and then blast it again and let it sit.
I had an O2 sensor that was stuck like this. After a few days of repeating the process I was ready to torch it. Gave it a third (or was it fourth or fifth?) dose of the PB Blaster and finally broke it loose.

So you trade 1 rusted bolt (o2 sensor) for 5 rusted bolts on the cat?

I second that.......And those bolts that are on the CAT are a major pita to get off too! Air tools are your friend there.
Though this might be your only option at this point if the O2 sensor is now stripped.

Another option....ever seen those As Seen On TV sockets where it's got a number of sort of loose rotating little rods inside the socket? A friend was able to use that to get a rounded off bolt when nothing else would work.
Third option, just say "F it" and leave it on the cat. It doesn't affect drivability, and is really only important when it comes to smoging the car!

Agree with this, I used my small mapp gas hand torch (yellow bottle). Mapp gas burns hotter than propane. Get a small 8" ish pipe wrench put a metal tube or your jack handle on the pipe wrench and after getting the o2 bung area nice and hot it should break free. Heat up the area where the o2 screws in because you want that part to expand so o2 comes out easier. Don't forget to put anti seize on the the new o2 threads in case you have to take it out later again.
