If CARB really cared about clean air they'd allow you to meet the clean air standard (tailpipe sniffer) however you damn well pleased - with or without a cat. If you can get your car to meet all the standards without a cat (I know a guy personally who had a 400+ RWHP heavily modded 951 that could do this because it was properly tuned), so be it.

CARB and the whole smog game has been hopelessly corrupted by greed and power. It's a giant money-making racket now operating under the guise of doing things for the common good. If you have enough $$$, you can get an exemption for damn nearly anything. If you don't have money, it doesn't matter what you do, you have to meet all their standards and (more to the point) do it THEIR way - even if yours is better!
