Just coded off ASD using BimmerCode, a boy what an immediate difference. I read this in another post, but your don't realize how much noise is getting piped in until it's gone. The cabin is actually 'calmer' and quieter in many respects, and you only hear what is real. The car has a more analog and realistic experience sound wise. You can also hear more of the stereo and music, without a thin bit of ASD interference. It's as if a thin veil of buzzing and synthetic car noise has been removed from the car.

Total win IMO and coupled with an aftermarket exhaust system really grounds the car.
