We have HF cats that can support 1200+ RWHP these days. And there are plenty of cars making crazy HP legally and even at that, they're making much faster and faster cars legally. So why is everyone soo stuck on the old silly illegal ways of doing things without even considering that we might be able to make the same or better performance legally? Not for nothin but companies like Roush, SLP, Calloway, Lingenfelter, and many others have been doing things this way for a long time. Even dealerships like LFP and others have been offering fully legal full warrantied brand new 700+ HP supercharged GTs for years. It can be done properly.
In any case, my ZL1 is already tuned to where I want it. I could go for more performance with more displacement and boost, but at this point it's not even worth it. My tuner/builder can get my GT500 to some pretty decent numbers while keeping it legal. My HC has the stock cats but I can get HF cats and LTs and squeeze a little more out of it. So none of this really bothers me too much.

Tightening regs man. It's the reason why the STI and in the 2 wheeled world, the Yamaha R6 are done. High flows do not remove nearly as much hydrocarbons as standard factor cats, which is why they are much cheaper. They do not contain nearly enough of the "precious" metals to do the job. At least this is what was explained to me when I asked a similar question years ago. Here in CA, it's gotten so bad that even if a tune passed smog, it fails if not approved by carb with an e.o. number.
