Turn it off and go for a drive Joe. You will be amazed how much different it sounds. After I got my car software updated, it defaulted back to ASD "on".
When I was driving home from the dealership, i was lke......man did that software open up the exhaust more ? Then I realized what it was.
With windows up and in Comfort mode, you cant even hear the exhaust at all w ASD off.
I bet your exhaust not alone sounds great without ASD.
