I don't know if it applies to the G05, but on my F90 M5C, you had to be in sports plus with the exhaust setting on (the latter is not a function on the G05) and then you would hear pops and burbles between 2500-4500rpm upon deceleration, and possibly only from 2-4th gear.

So if I was cruising slow in 2nd gear, and at 4400rpm lifted off the gas, it would pop/burble instantly, every time.

I don't know if the G05 has similar parameters that must be met, but I'm betting that being in Sports or Sports Plus is probably one of them.
