Honestly cannot say, I destroyed a stock cat at 8PSI after about 30k miles.
The added heated will destroy them faster but at what rate will depend on how much you drive, how hard you drive, etc.

How did you know it had gone bad? Did you see a loss in power or did you hear the exhaust note change? Did it smell like rotten eggs?

Exhaust had an odd noise, a little rattle like something was loose (which it was) so we checked it out and it was falling apart on the inside.

I too have been very curious about this same issue. ...Like TopGunZ all my reads on this topic have been conflicting.... also read in Swiss370Z's thread that his stock cats gave out....the pic was crazy. ....so even at 8PSI the stock cats broke down for you (Dreamer)? So is it definitely better to go stock cats vs HFC'S with a S/C? I have read of people runni g HFC'S that are ok while some with stocks blowing out...Has anyone experienced actually blowing out an HFC with the S/C?
