CA smog tests--how long until the first one?
 

I'm thinking about putting on a bunch of Stillen parts, and it says that some of them may not be CARB legal. How long do I have until I have to get my first smog test? I heard six years, but that was just someone's opinion. If that's the case, I'll probably go ahead and put them on and just take off the offending ones just before the test.
