I have the Yakima EZ Riders. I have not found the noise to be bad. I initially had the bars and a Yakima fairing and noticed very little noise. Now, I have a Yakima cargo box on most of the time (with no fairing) and there is some more noise. I would say that the sun shade provides a good deal of noise insulation. When I put the sunshade back, the noise is much more noticeable. You might find yourself keeping it closed (unless you want a good look at your bikes). Also I imagine that the bikes might create more noise as my cargo box has some aerodynamic shape to it.
