It's not just Kooks it's pretty much any ceramic aftermarket cat. It seems to be hit or miss with them. My buddy has a set of Pypes ceramics he had 1 fail after 80 miles or so. Pypes replaced it and sent him a hat and bunch of stickers lol. I'm pretty sure he's got about 8k/mi on them by now, no issues.
Magnaflow makes a metallic cat. IMO if you gotta have cats, I'd go with them. Especially if you're really going to flow CFM like a boosted car will. Pricey, but you get what you pay for.... right?
Personally, O/R X all the way. It's still "somewhat" quiet, at idle...
