My 330e's OEM exhaust has become louder than it should be

Hi!

At the beginning of lockdown, I found out that the exaust became very noisy, in particular when the engine is cold. I have had the mobile engineer despatched and they weren't able to identify any issue - neither by checking errors, nor visually inspecting the exhaust (it sounds as if there was some sort of of a perforation).
They advised to have this checked once possible.

I have now dropped off the car in the garage, but they say they don't see anything wrong. Yet it still apprears to be more noisy than it should be (I have made some recordings - feel free to check below):

In any case, this is much louder, than when I picked up the car brand new.

Did any of you experience similar issue? Do you think the noise on cold engine is more than what it should be?
