No... When running empty up top it makes no excessive noise but you know its up there... But then the Disco is hardly then quietest brick to push through the air anyway!..
I find all my excessive noise comes from the contents of the car that are using the seatbelts!!!!
My load layout up top is what has caused me noise factor as such... Due to the load I put up there I can't really adjust it much. I may try a wind deflector but I prefer the 'look' of the basket stepped back from the front end... Also stops the window washer juice flowing onto the contents as well..
I have been in a Disco without the bars and a full rack up top and the noise is the same...
Either way you go... There WILL be noise from uptop mounted goodies...
