I know somone that wants to sell a Tubi for a Diablo. (It is NOT mine) Would you know anyone that would be interested? If so, PM to me and I can get more details and put you in contact with the person. The piece is in Florida.
I can send a picture and of course I have a price! Asking $2,300 plus shipping. I was told that it is the "louder version" for the Tubi. It also comes in what they refer to as "standard".
