I did not know there was a factory option for a pop up wind deflector on the Cali top. The wind noise with the side windows up is horrible. I added an after market deflector that helps some. Mostly I have the side glass down when the Cali is open and it's not an issue. Now if you want to talk water leaks down the A pillars- that's another issue. As one enthusiast said to me- it was meant to be used in CA and it does not rain there
