    Thanks, you verified what I thought was happening. After driving many miles I thought I heard the exhaust going quiet after going into 4th gear on the A8. Glad to know it is normal.

    Nice, I’m after more burbles when letting off the gas, looks like at least in the video this will do that and it’s noticeable from the outside, can you hear those burbles from inside the cabin? I hear them slightly in track mode with the fuse still on but I’m wondering if removing the fuse will make the burbles louder

    If I pull the fuse will the exhaust valves still close on stealth mode?

      No. Pulling fuse disables all power and ability to control the valves.
