OK...new question (and thanks for the responses to my first posting).

Exactly what is the difference between PZEV Foci and non-PZEV? how does this affect modifications such as cold-air systems and cat-back exhaust systems?

I don't know how I managed to get one of these cars, since Texas is a long way from California, but I did, and am wondering about how and why I am down 6 hp from the non-PZEV cars.

I can speak for Subarus, not Fords, but on Subarus, it's some additional emissions hardware that adds about $200 to the MSRP, and otherwise doesn't affect anything, cuz I know people who added catbacks and stuff and nothing was different as far as when they bought aftermarket parts.

It's not just CA that has them, they're mandatory in a few other states and the list is growing.
