My Kooks high flow cats are holding up great so far at around 750whp. They have around 10k miles including numerous track days. I dropped my exhaust last weekend when I installed the FE4 handling kit and ZLE cradle bushings and the cats still looked like new. Based on Greg and other's experiences, I must be right at the limit boost/hp wise.
