Hey there. That's a bummer about the wind noise from the OEM roof rack. It's a drag when something meant to enhance the car ends up being a nuisance. Have you tried adjusting the rack to see if that changes the noise? Sometimes it's just a matter of getting a tighter fit or a different angle.
On another note, if you're open to alternatives, you might want to look into the
Tesla Model Y roof rack from TESERY. It could be worth a shot to see if it offers a quieter ride. A few folks have mentioned they've had a better experience with it in terms of wind resistance and noise levels. Hope you find a solution that lets you keep that unique look without the whistle!
