Perfect, yep that's what I remember reading. Out of curiosity do you know the default value or if changing Drive Select mode does indeed change it?

I do not, as I have not investigated that (I merely muted it.)

I muted it as well. Search YouTube for Soundaktor demo videos where people attach them to various objects and play music through them.

Drive Select -> Engine Sound -> Dynamic
Switching to Dynamic mode in the A5 doesn't seem to make much difference in sound, power, or handling. I wonder if it works better on the S5's.

If you want your exhaust actually louder then unplug the exhaust pressure valves by the mufflers. They will remain open all the time. Mine have been this way for 9K miles. "Dynamic" exhaust sound still has the left side closed a lot of the time. I think it sounds much better with them open. Also, Sport mode still makes it a little louder and adds the crackle sound. I believe they do this with a slight programming change to allow a little overrun.

Yes!! This is what I was looking for. Just so I don't screw anything up, can you please tell me/show me the steps to unplug the valves? Thank you!

Have you considered installing Whistletips? I think you source them from Rubb Industries.

I certainly hope these do NOT become popular in my neighborhood!
