California headers and smog

Hey guys, I live in California. A buddy of mine said when you get a smog check they don't inspect illegal parts, they only check emissions. The parts are only illegal if the police find them, how true is that? I want to know only because I'm about to buy headers, but don't want to be forced into buying BBK shorties. Any info or experience is appreciated.

I live in Cali have carb approved items: bbk shorty headers and (hopefully soon) procharger supercharger . I've heard even though they are carb approved they can still fail "emissions". So I'll have to see what I can do when the day comes.

BBK shorties are definitely the safe route. I for sure wouldn't do long tubes because you'll fail smog automatically due to the original cats being moved.

You could straight pipe the car and it should still pass the tail pipe test.

If the components are CARB approved, they should not cause you to fail a smog test. The key is that the aftermarket components that are around the emissions system - have to have a CARB sticker or CARB number on the product.

Guaranteed if you are pulled over by the police, and they have reason to inspect your car and they find long tube headers - count on a ticket. With all of the street racing going on, they are inspecting cars to crack down. They are getting training as to what to look for.

BBK and JBA both create shorty headers that are CARB approved. No long tube headers have an approval.

Thanks guys! I'll probably just go the safe route and do BBK ceramic shorties. Maybe a custom H pipe down the road and leave the exhaust alone after that.

Bbk and jba are the only carb approved headers. Both are shorty, but the good news is this car responds very well to them under the curve even though peak gains are only 8-10hp.

I do not think they have a CARB number.

High flow cats aren't legal in california. So pretty much no aftermarket mid pipes are unless they bolt up behind the stock cats.
