Whistling noise

[damesaprotege]

Hey I have a problem..really though, I have a 04 3(sedan "i") slightly modded ofcourse, when I drive over 120km or 75mph for you americanos I get this loud annoying high pitch whistle noise and I can't seem to find it, it sounds like it's coming from the front through the firewall. Anybody experience this problem before. Any help would be appreciated. Also my IMRC is fualty any luck on this topic???
thanks

IMO, you have 2 possible causes:

1. Door seals
2. Window not rolling up fully or correctly
