Metal Scraping Noise

[jasqi]

Alright so to start off the noise it’s making is a sort of metal scraping sound, almost like something is dragging. Here’s a video of it:

 

Now I’ve checked the turbo, the exhaust, and looked for anything dragging and all seems good. What in the world could this sound be? The noise presents itself when letting off the throttle, noise does not change when brakes are applied, speed effects the speed of the noise, neutral does not change noise, clutch in doesn’t change noise, the noise entirely dissapears above around 50, noise is mostly eliminated whilst accelerating.

 

Any ideas are much appreciated.
