I think you're going to have to look at that exhaust properly, bitch to get to though it is. The volume doesn't seem to be any different between the two vids, if the compressor/turbine were touching then it would scream with the intake open to atmosphere. Definitely isn't a boost leak since it's the same with the boost pipes off. The noise happens when the vanes are going to be closed up, ie when exhaust mani pressure is highest, so have a good look at every connection upstream of the turbo. A mirror and a good work lamp are your new best friends lol.
