Chunk of Cat in Exhaust

[TM]

The cats often fail in this manner- you'll need new cats- that's exactly
how both of mine failed.

While doing exhaust work on my recently purchased 200q20v, a chunk of
cat. converter substrate was found in the left exhaust pipe before the
middle resonator.

I figured that the cats would need changing (orginal cats, car has
140K), but this seems like it is not the normal way a cat fails.

The car pulls 1.8 bar and has a IA III+ chip and right now runs great.
Any ideas if an anomolous engine event caused cat explosion, or is this
a sign of something more chronic?
