2008 Impreza Roof Rack Noise

Hi, Sorry, I should have give a more detailed subject line to this post. Here's a repeat: Has anyone heard of Subaru-installed roof racks on

2008 imprezas causing a lot of noise at speeds of about 40 m.p.h. and above? Also, what about roof racks in general? Are there other makes out there that fit on a Subaru that can be taken off and put back on when needed? Thank you.
