A8freunde member Tennohund modified his exhaust by removing the H-pipe and putting straight through pipes (I think) through all the boxes.
He achieved a very nice sound (IMO).
I cant find the original post on A8freunde forum where he posted pictures of the modifications, but he has re-posted a picture on another forum.

There were several youtube videos with apparently no serious drone.
Only one video remains its been re-posted after the owner deleted the originals. This one does not show in cabin so can't judge for drone.

I copied the photo from the other forum for future reference in case the thread gets deleted.
