Puking CGT

[David]

My 1987.5 CGT started puking out bits of catalitic converter matrix out the tail pipe. Pretty large chunks at that. No clue why, I haven't hit anything. Will having a "bad" cat cause any real problems? I would think not, and that all it could do is give me a pony or two from being freeer flowing, but I've never had a cat self destruct before... They don't do smog testing here, so that's not a worry, but I don't want it to cause any damage... Thoughts?
