Post a sound clip so that we can possibly diagnose it better

take it to the dealer. your car is still under warranty.

The turbocharger that comes with the car isn't ball bearing so the answer is no.

Might be bad gaskets for stock header even though you didn't change anything.

Are you sure its coming from the engine bay? It might be your side mirrors or weather stripping. This has been previously reported

it's absolutely stock, so no bov, no intercooler piping, etc.

cuz it sounds like a bolt is loose or something somewhere, like there is a small boost leak

seriously you should take it in to have it looked at if you have only had it a month. it should be still under warranty so just go get it looked at. might wanna take off the intake first

seriously post a sound clip. if you have digital camera just record video and post it on youtube and post link here. if it's that audible the camera will pick it up

are we sure that this high pitched noise isn't the turbo spooling?
