'Squealing' around 80-100mph

[200 Alex]

I'm pretty sure it's a wind related noise but I'm not sure what's making it.

Comes in at the mid-top of 4th gear then fades away after a few seconds.

I have changed all the engine mounts to ktec ones. Not sure if that makes a difference.

Any clues?

sunroof? or mirrors?

Try pressing up on the roof lining near the interior lights when it happens. See if the noise changes pitch.
