wind noise/flapping after washing car/rain

Same we have a 2021 z71 tahoe and after rain or car wash. It comes out of both sides making the noise I have read there is a extention for the drain hose for the sunroof and you need to add the extended hose because otherwise what is currently in there is allowing to much pressure to build up and not allowing the water to properly drain which is the noise we are all hearing. Not sure how this is done yet I am researching it now and once I find out and have the extended hose added I will update if it fixes the issue.
