Sorry if this has been covered but I couldn't find it if it has. Proud owner of a 2021 Cayenne It came with the roof rails but was wondering if anyone has researched and/or have opinions on cross bars. I guess also asking if you purchased and installed aftermarket cross bars, which ones did you get, and are there any issues with them(wind noise, durability, installation issues, etc). I understand I could look at reviews on Amazon but those aren't specific to people who installed them on a Cayenne(particularly a 2021)... so I'm seeing if there's anything specific another Cayenne owner can bring to my attention. Thanks!!
