I love it -- at idle, subtle difference, but when you get on the throttle, it really comes alive, very deep sort of throaty pitch to it, not fart can at all.

at highway crusing speed it's pretty quiet, you know it's there, but no droning.

Around town, RPMs below 2500 and you do get some droning. I drive in sport mode, so it's not an issue for me.

No sound clip yet, will try to get one soon.
