The cool flo can not be carb legal, it uses a breather filter for the PCV. The only intakes I'm aware of with CARB certs are the AEM short ram and the K&N FIPK. A black iceman would probably never be noticed, though a colored one might raise suspicion.
For exhaust anything goes as long as it is after the cat loudness is the only legal issue. There are 2 headers that are CARB legal, JBA and Edelbrock. I've seen the CARB #'s on the actual units. High flow cats are a grey area. The catalytic converter cannot be moved from its orignal location and can only be replaced if "needed" (ie orinal cat gets damaged or something) before 50,000 miles. After 50k miles it appears that replacement is legal.
as mentioned above internal stuff is only a problem if you don't pass the sniffer test. I'd recomend cams with minimal overlap (Kents from FocusSport for example) for best chances of still running "clean".
The thing to remember about CARB is that actual emmisions aren't their priority, if it was why would you do more than a sniffer test. Clean is clean, no? They are staffed with anti car fanatics who do everything they can to discourage car ownership. Anyone recall the the 50cents a gallon tax on gas, 3 cents per mile "road use" tax and $3500 surcharge on Trucks, van and SUV's they were and still are pushing for?
