I can tell you that I've blown OEM cats and high flow cats on my supercharger set ups on a couple of occasions. Especially if running rich. My current fix is running resonated ART pipes and moving the Cat cells further down the stream. (Suggested by Seb @specialtyZ).
I haven't installed them yet, but I'm hoping to lower temps as well that is causing timing to get pulled when IAT's climb in WOT. Should have some logs in a couple weeks + retune for it. I'll post results
