Default Catalytic Converter - Clamp it, weld it or replace it?

So when I stomped on the gas the other night I heard - and felt - a BAM, and then the world became very noisy. I could just barely hear my daughter laughing at the situation. Here’s what happened:

So my question is this: can I get a stainless steel seal band exhaust clamp to reconnect these two tubes, can it be welded back together, or do I need to replace the catalytic converter?

If I can go with the clamp, what size should it be - 2 1/2 inch?

If I go with replacing the whole thing, is it bolt-on or is welding involved?

Since its extremely loud, I don’t want to drive it around to muffler shops for estimates, so I’m hoping anyone can pass along suggestions.

I've never done any welding, but do you think there'd be enough metal to weld it back together? I'd think there's too much rust to melt it back together again.

As for replacing it, has anyone replaced the cat and can give me any pointers? Seems I just need to jack up the car, remove the O2 sensors, and swap out the cat - but am I missing anything?

You may have a plugged catty. I would go to a local muffler mill and let them cut and weld one on. That should cast under $100.

You should be able to see down it to check if its plugged. Its pretty rusted but you might get lucky and be able to weld it back up. Depends on the pipe condition.

Take it out ;-)
