I have it on 335xi...My family can't stand it...but I love it.
I'm not sure its for older adults who like a calmer ride. It is quite loud and it does resonate in the cabin on throttle.
Ie. there is a low rpm bellow on open throttle at 2000 rpm...it turns into a nice high freq engine sound at 3000 rpm.
