how robust are these cats at say the 600-700 hp level on e85 and 93 octane?... assuming you have a good tune.

My cats were on my previous car in the 650-700 range on 91. They're still on my current car, but I've only been over 600 about a year or so. More recently with E85. I think the biggest thing is don't turn off the cat protection in the stock ECU.
