I am supercharged and run the oem cat . Have done so for over 60k without issue . It does cost some power but i think it's worth it . No smell from the exhaust is a huge benefit in my opinion .

With around 450 whp no cat currently on the market will last I plan to use a core for the German dtm cars to make a true high flow cat that won't melt but the core is 650$ so it will be awhile. It will be 70mm as I can't get it smaller than 3'' in and out. under 400 whp with a afr no lower than 11.7 should give you some miles before it starts to eat itself. my stock cat with stock comptech kit only lasted 20k miles by then it was robbing 50+whp.

I wonder if a cat from a factory vehicle that normally puts out high HP could be adapted to last on a 400 whp track s2000. A vehicle like a gas powered motorhome or gas powered truck.

it would need to come off a gas forced induction vehicle as n/a cats aren't designed to put up with the rich air fuel mixture that's what kills them too much un burnt fuel in a hot cat causes the meltdown of the core.
