I get a strange high pitched whistling sound from my 03 Forester XS under hard acceleration. It sounds matched with the RPM's, not the speed of the vehicle. It only happens when I'm close to full throttle, not under normal acceleration.

Does anyone have any idea whether this is normal?

Check your exhaust resonator, mine was doing that before the welds pulled apart.

Is it coming from your speakers?

Nope, definitely not the speakers. The exhaust resonator sounds like a good suggestion, will look into that. Thanks!
