52 to 62 mph low whine or soft low pitch whistle......(I did search)

That's it....... very low volume. If I slightly let up on gas, it goes away, even when between the two speeds mentioned above. If I slightly accelerate, it goes away. Sounds a little like the way some new tires "sing". If I turn UP the radio, I can't hear it. I'm just curious,,, not a major thing. Air intake?? Any solution???

I think I know what you are talking about. My GT makes sort of a quiet whirring sound at times. I also have a CAI and exhaust, but I remember it making the sound before the modifications. What model do you have and any modifications?Welcome to the site.

Thanks Justin, Just a basic, basic Vibe w/auto trans. Too low pitch to call it a whistle, but kinda like the sound of "rushing "air..... just audible....
