Cats with Superchargers

I saw the post below from Topz about HFCs in another thread, and was wondering if there might be more long-term data available from various users?

The logical part of my brain wants to catalog the failures into specific reason(s) *why* the problem occurs. I hate it when things happen "sometimes!"

I'm guessing that the difference between sc and turbo applications is that the turbo somewhat mitigates some of the pressure/flow in the exhaust? For the ones who blew their stock cats, is there a common mod or circumstance that seems to precipitate failure?

I recall reading in one of the threads that the stock cats are 400-cell, so does the cell count not have anything to do with the flow capabilities, say, compared with a 200-cell Berk? Sounds like if you do take the plunge in upgrading to Berks, that you should save the OEM cats in a box...just in case.

What do the manufacturers have to say about their HFCs being used in sc cars? Do they stick a clause or two in the warranty to limit their liability?

And, on a purely practical note, does a cat give the driver some advance warning when it is blown, or is it possible that chunks could catastrophically get thrown into the muffler with no time to limp to the curb?

Thanks for your input!
