IIRC all four are actually fully functioning no the california.I think you will be disappointed to know that BMW and Mercedes Benz are follow the Lexus lead and utilizing "fake" exhaust tips on their newest offerings. The exhaust is no longer connected to the metal tip which is integrated into the bumper cover.
So is Ferarri juvenile for doing this to their car?
Has it been covered, if I make the extra two ports funcitonal, will it effect the exhaust tone negatively? I guess that's sort of subjective.
