Weird squeacky noise...

I have a weird noise that I have trouble diagnosing. Most noticeable in first and second gear when 70-100% throttle at 2-4k rpm. It's like a Metal squeakyish sound similar to what a spring mattress/couch makes. Only thing that comes to mind is that I have no catalytic converters on the car and instead have a straight test pipe without and flex-joints. Other then that I have no clue. Heatshield on stock turbos is solid so it's not that either.

I call it the girlfriend :D

 

Haha, I wish!

 

Throwout bearing?

 

I doubt that.

 

Is it coming from the back? Check the boot rubbers (rubber blocks) they go hard with age.

 

I am pretty sure it's comming from the engine compartment. Can the manifold crack and make any weird sounds?
