I've had my FD about 2 months and it drives great, pulls well, and all that. Only about a week or two ago I started noticing what sounds like a metal rubbing on metal squeak. It only happens during easy driving. I always let the everything warm up until the temp guage reads over 175F (aftermarket obviously). If I'm doing roughly 35-40 MPH in third or fourth gear (on flat ground or an incline) and I press the gas to the point just before where if you press it anymore you know the turbos will start pressing. When I do this it makes the metal on metal noise. I've been driving around trying to listen and see what the sound could be. I originally thought it was maybe the U-joints or the wheels (moving parts besides in the engine bay), but I wondering if it's the turbos (maybe out of balance). The thing is both primary and secondary boost fine with a 10/11-9-10 pattern. Any ideas? Anything I can check or look at to see if it is the turbos?

Also I have a dp and cat back and its not the normal noise of the turbos spooling.
