R50 Mini Cooper 04 vibration driving me insane

As the title says, I ve been trying to get to the bottom of a loud metallic rattle/judder coming from my MC. So far these are the symptoms:

• The car will make the rattle at idle, both with the clutch up or the clutch down, immediately when cold.
• After running the car for a bit, or driving consecutive days, it will sometimes go away.
• The sound is strongly coming from either underneath the car or the back bottom of the engine.
• When I press the accelerator and bump the revs, the rattle immediately stops but comes back once the revs get low enough (clearly feels like something resonating).

Here is a video of the sound (both videos were taken on the same occasion that the noise was happening, I can t hear it from looking down on the engine but can clearly hear it in the cab and underneath the car)

I got under the car today to check for loose heat shields or underbody plates and couldn t find anything. I ran the car from cold to try and see if I could locate the noise and of course this time it made no noise. Any ideas welcomed.

Thanks

[text]For anyone interested this turned out to be the exhaust (baffles broken I believe). I’ll be replacing the exhaust which should hopefully fix the issue[/text]
