ASD disconnected what a huge difference.
Featured on BIMMERPOST.com Everything sounds more natural with the exhaust note traveling out and behind the car. I can definitely hear more upfront engine noise almost to the point where it reminds me of my old E46. Highway cabin noise levels are more comfortable and the HK system even sounds better. One thing I also noticed is that the rev matching is considerably quieter as well. Meaning, I can see and feel the rpm's jump, but audibly it's now extremely subtle. I most likely will get it coded out, but for now its unplugged wrapped in a small micro fiber towel with a zip tie to keep it from banging around. Definitely not going back.

Couple threads on this already, but I agree. I can't imagine why the M engineers even bothered to include this in the car. Even with stock exhaust, it sounds perfectly acceptable without ASD (and better, in my opinion). Preference is subjective, but I'll never understand what BMW thought this adds to the driving experience - to me it sounds freaking weird.
Enthusiasts hate the concept of speaker engine sounds altogether, and non-enthusiasts usually want quieter cars inside. To me, it seems like this was a feature no one asked for, especially on the M model. At least make it a toggle in iDrive. |

Rev matching is is quiet because the valves are closed for downshifts unless in low rpm's.
