High pitched whine at high rpms

Mine is an 05 hemi. I got under the hood last night, pulled the belt and played around with the pulleys. The power steering pulley seemed to have quite a bit of play, I could wiggle it maybe a quarter inch back and forth, plus I noticed that the pump and most of the components in that area were saturated and way more rusted than anything else underneath, although my power steering fluid is still full. I think I may have found my problem. The whine mine it's making is very loud but it doesn't whine when it's idling, only when I rev the engine.

Would most definitely not be an exhaust leak...
An exhaust leak would make an intermediate hissing sound. The whine is possibly the air rushing into the engine??? I don’t know, but I think it has something to do with the alternator or power steering. My car has a 5.7l and it only makes the noise when flooring it/above 4000 rpm.
