I installed the asd delete cable; took 30 minutes, this weekend.
Drove it to the office this morning. I absolutely love it!
I can still hear the exhaust and enjoy it without a problem, especially if I open the windows, and the radio sounds so much better! I really wonder what the BMW engineers were trying to accomplish?
The backfire "pop" sound when coming off throttle is much more subdued and that is fine by me! There is a similar backfire pop engineered into my 07 Mini Cooper S which isn't piped into the sound system and I will admit i do prefer this "au naturelle" (apologies to my french colleagues) sound much better. The ASD amplified version sounds too artificial.
Also when I got to the office my hearing was much improved!
