Wind noise
If you have older or even the original weather seals on the vent, cabin openings and quarter windows - and that's a lot of rubber - they will have taken on the imprint of the glass as well as hardened and cracked so when the alignment changed how they contact the glass you get more and possibly new noise. Given the absence of a B pillar and all the operating glass these are going to be noisy anyway.
Nicad's idea of taping off areas to identify the worst individual sources is a good one but in order to do something about it you probably have to start replacing some or all of the rubber which is somewhat costly and will have a learning curve in the technique.
Other alternatives may include a louder sound system (more money), more power (fun but costly), louder exhaust (no muffler will save money until you are ticketed), drive with the windows down (mask the wind noise with, errr... wind noise) and earplugs (very cheap). I have the first option but am almost deaf as a result.
