Sound generator z4 3.0 e89

What sort of sound generator are you talking about?

Mechanical or electronic?
 
Hi thanks for replying Mohawk and Pbondar .
I’m talking about mechanical ones like on previous model
3.0si I think , I’m looking for a bit more noise from the engine inside .
My car is bone stock and is a bit to quiet- could anyone recommend modification to the exhaust ? Don’t want to make it to loud
Thanks
