Hey there. I am trying to diagnose this weird noise my car makes when i drive it. here are the symptoms:

-sounds like a turbo spooling
-only happens when the petal is pressed down more than halfway
-doesnt matter which gear
-doesnt matter what speed
-doesnt matter what engine temp

Could it be a hole in the exhaust somewhere? Its very audible from the inside of the car and even more so from the outside. I can post a video if someone has a clue of what it is? Anything will help.

Thanks, Dave.
