I’m using these and they look great, no noticeable wind noise. I’m also using the $90 harbor freight roof rack, which has noticeable wind noise above 50 mph.
Highly recommend these bars. Fit is as good as OEM for half the price

I bought the Brightlines Aero Cross Bars off of Amazon for $100.
Easy to install and look great.
We bought this and have zero issues. Great fit and no whistling.

This one is built in the same factory and is identical to the Rhino X-Tray for about $100 less. I love it, have transferred it to two vehicles, climbed all over it, used it on two cross country trips! First thing I did after putting it together was sealing the entire basket with a few layers of spray on bed liner giving it extra durability. A good tip for these if you want them to last long is to not keep it on 24/7 unless you use it enough to warrant it. We do a ton of traveling in Alaska so we have a extra 8 gallon fuel tank mounted in it for extended driving out in the Arctic back country. The gas tanks are stackable so with one more I can double my range and still have room for a sportsman trunk up there. I just use it with basic Aero crossbars from Amazon that I also sprayed with bed liner and I'll also link below.
