Have you done a dyno run or are you just guessing?

Dont mess with the intake. This isnt a cheap car. BMW put a lot of money into the factory air cleaner and you will not see gains with this aftermarket one.

Is anything aftermaket legal in California?

I think the stock intake is actually rather quiet. You could disconect the hose from the air filter box to hear what it would sound like without the factory air box. Just dont drive around without putting at least a cone filter on the pipe.
