Propshaft vibration

I am getting a vibration/drumming when accelerating hard in 2nd and 3rd but only once the car has been driving about 10mins. It's not speed related only torque, subframe bushes and diff bush have been replaced. Now is this the propshaft coupling, centre bearing or gearbox mounts?

Most probably its the center bearing
Exhaust off, prop off and new bearing im afraid

I'm not saying it isn't but if it's the bearing why doesn't it show up at different speeds or high speeds, 120mph no sound at all?

Just popped to BMW and they are also confussed as to why the running time makes any difference. So I am replacing the ECP parts with BMW parts (prop coupling and gearbox mounts) and see if this makes a difference.
Oh well at least everthing will be new by the end of this

The propshaft coupling was split and generally fubarb. It was only 2 years old from ECP what a pile of junk, only BMW parts form my baby now.
