okay i have a 2001 SS M6. The car is basically all stock except for the slp dd exhaust and an mti air lid. When i am at highway speeds around 65-70 mph there is this high pitched whistle noise that you can hear with the windows up. When I let off the gas it goes away and when I barely touch the gas pedal you can hear it. I just barely touch the gas pedal when it starts making this whistle noise. It sounds like to me that its coming from the passenger side of the car. The noise starts to fade off around 80 mph I believe or i just don't hear it because my exhaust overtakes the noise.

If anybody else has had a noise like this please inform me as to what it is. It is just driving me crazy.

check your vacuum lines. I had a rubber fitting go bad in my old car and it did exactly what you are describing. Replaced the fitting and it was quiet again.
