Assuming it’s due to corrosion, am I correct that that whole section of exhaust should be replaced? I usually source my parts myself if I can. Any recommendations or things to avoid?
That section has been welded before. I’d have an exhaust shop cut, replace, and weld it again.
Is there a piece left between the cat and the exhaust pipe or did it break off flush?
Flush as far as I can tellYeah that’ll be a replace of at least the cat now unfortunately.
If there was a stub you can re-clamp to it and check for leaks. If there isn’t one you’re good to go until it falls off again.
I was completely wrong when I looked yesterday. I don’t think it s as bad.

That’s not a catalytic converter that’s just a resonator (or possibly muffler) to set the exhaust tone. A cat is further up toward the engine and has O2 sensors before and after it. You can probably just clamp it for a while but the proper fix is to have a new resonator/muffler put in or have it cut out and replaced with a section of pipe.
You can probably weld or jerry rig this together with clamps in a pinch, but you should probably replace. Unfortunate it looks like Toyota designed it to be one pipe - sometimes these are separate pieces that are cheaper and easier to replace.
A piece of stainless steel or aluminum duct and a few hose clamps will hold this together long enough for you to forget that you rigged it when it breaks again and you actually have to replace something.
You might be able to get away with cutting out a section and clamping a new piece on.
If you do please check that there isn’t an exhaust leak.
That’s well fixable. I got a stainless steel toilet brush holder and cut a cylinder out of it, cut it down lengthways and wrap it round, with some GunGum underneath. Four heavy duty jubilee clips to hold it in place.
