Annoying whistling noise from the front?!

[TL24]

I have a 04 Yukon Denali and I've been hearing this "whistling" sound coming from the front end when I'm going about 50-55mph and above? It's loud enough that when you drive under a bridge of some sort you can hear it bounce off the wall back to you. It's really annoying and this happens whether the car itself is hot or cold (not driven for a long period of time).

The weird part is that this "whistling" sound ONLY happens during higher mph and not when I'm going 45 mph or below. What could the issue be? I'd like to try and resolve this damn issue asap if possible.

Thanks ahead of time guys!

No suggestions from anyone?

Do you have a bug deflector? Mine whistled a little and I adjusted the bump stops for the hood a little and it raised it just enough to make it go away.

Oh wow, now that you mentioned that I just realized I do have a bug deflector on the hood LOL... I'll give that a shot and get back to you on that! Thanks man!!

Swiss-cheese mod to your air-intake?

Mine, at the right RPM's anyway, makes a bitchin' whistling noise that sounds a lot like a turbo spooling up. It's kind of cool, actually....lol.
