I plan on going OEM with my Odyssey. Have Rhino Racks for my 2010 Fit Sport. They work great but there is a ton of wind noise since they attach to the door jamb. I expect much of the same with Rhino Racks for the Odyssey. I also have a 2003 Yukon with roof rails and factory racks similar to what the OEM Odyssey setup is like and wind noise is not at all noticeable.
