Exclamation Loud, Obnoxious Whistling Sound!!

I have a whistling sound that is much louder than standard turbo whistle. I tried unplugging the wires to my turbo and it stopped. Plug them back in it starts agian. It is pretty much only at an idle. A lot of times if I push the brake pedal all the way to the floor it will stop temporarily or if I turn the steering wheel. It also goes away if I increase the RPMs. Occasionally when I first start it I won't get the whistle until I actually press the go pedal to accelerate and then it goes away quickly.

I'm thinking maybe up-pipe. And by doing these different things it is dragging the motor enough to change the airflow.

Any ideas?

Need help ASAP!! This noise is has me and it is embarassing to let my truck idle. Even at a stoplight.

I can't figure it out either. I have searched threads on here but haven't found anything that describes the issues I'm having.

After looking at it this evening, I'm pretty sure it's the passenger-side up-pipe. There is black soot around the upper folds of the flex portion of the up-pipe. I used a bar to press on that area while the truck was idling and when I would hold pressure on it, the whistling would stop.

Now I just have to figure out the best way to fix it. I am thinking about trying this mod:

Up pipe

I'm assuming I would need to get another up-pipe that is not cracked though. Any suggestions?

Thanks. You can't buy anything for these trucks for less than $350.
