Problems with B pillar at high speeds..

I got up to 115 tonight in my Civic EX. As soon as I hit 115, I hear a huge rattling noise coming from the proximity of my B pillar. And now when I get above 85 I hear small squeaking sounds.. any ideas as to why?

The only thing I can think of is the outlet where the sunroof let's out.. I figured it might just be the speed of the wind going through it and rattling it around inside.

Ok I think I figured out the squeaking sounds. I went to check the lining on the edges of the windshielf, and the rubber seals on the side of the windshield seem to lift a little and move back and forth, which make a small squeaking sound.

The rattling, however.. I don't know what caused that.. my best bet is still the air flowing through the sunroof outlet.

Any ideas?
