So while driving, there is an occasional whine that I personally hear coming from the passenger side when the gas pedal is pushed between a certain threshold. I hear the whine when the pedal is pushed 5% - 10% of the way to the floor if that makes sense. Other than then, I never hear it. I'm stumped so any tips would be greatly appreciated.

Hmmm...
Is it a manual transmission? And what gear? Does speed matter?

Just because it’s important, have you had the exhaust looked at on a lift for leaks? A hiss or other noise would be more likely, but maybe a heat shield could vibrate, besides a leak.

Yeah its manual, the T-45. Speed and gear don't matter. But it doesn't do it when in neutral. I've not had the car looked at for leaks; but I have an offroad x-pipe in right now so cats/heat shields are out of the equation. The whine started a long while after installing the x-pipe though.
