I recommend the Thule Aeroblade Edge bars. Not only are they extremely quiet compared to other bars, since they are low proile and have a wind diffusion strip, but they also have what is called a t track system. The t track system allows you to add accessories carriers to the bars without needing to bolt the accessories AROUND the bars, they simply slide INTO the bars. This allows you to swap carriers on the fly, between kayak or bike or cargo rack, as well as open the panoramic sunroof without running into any mounting hardware. I don't have personal experience with Thule 's kayak carrier but they are a very reputable brand so I'm sure it is top of the line. I do have personal experience with the Aeroblade Edge bars and thules bike carriers and cargo rack and can't recommend them enough.
