I think the BBK shorty is CARB approved. They do not list anything on their website though... You might want to call them first.
However, JBA makes a CARB approved shorties as well, albeit for about twice the cost of the BBK.

Unless your stock manifold is cracked or damaged I wouldn't bother changing them out. The stock manifold flows plenty well for most anything you can do with the car.

Here are the headers:
BBK Performance 4008 - BBK Shorty Headers - Overview - SummitRacing.com
JBA Headers 1619S-1JS - JBA Headers Cat4ward Headers - Overview - SummitRacing.com
