Even if there are catalytic converters in place, I don't think you are "legal" in california unless the items you use to replace the OEM components have a CARB EO (California Air Resources Board Executive Order) issued for them. That said, a catted header with the O2 bungs in the proper locations should prevent any CELs from bring triggered so, from that perspective and the inherently cleaner exhaust you'll get out of the tailpipe, there's still benefit to the aftermarket units beyond just power and sound.
