Kooks website says that their standard cats are not to be used with forced induction. Their green cats do not have that warning. What is that all about?

Funny, I've heard the opposite from builders and tuners. My standard cats are doing just fine, I just redid my exhaust and inspected them.

I’ve seen lots off issues with them, personally I would look elsewhere.

On my old stainless works setup I melted two metallic cats. they looked like a baseball made out of tin foil. The internals that is.....not the entire cat
