It also happens to some OEM cats. One of the catalysts blew out on my girlfriend's CLK 500 when she hit 70k miles. Covered under warranty (OEM emissions system is covered to 80k per federal law).
Point is, any name brand cats are no more risky than factory, and a fail of a tune is the main reason, not the HFCs.
