I'm only going on info I was given here locally by our performance shop mechanic who tells me there has been a history of SC cars that are tracked needing cat replacements after 3 -6 months.
Our fuel is different and there may be other factors I'm not aware of that could relate to local conditions affecting these vehicles.
I've had HFC and full catless and found gains with a full catless system with the same X-pipe and rear section.
