Finned exhaust collars

[CB1100DLX_imp]

Hi, has anyone installed finned exhaust collars on their CB1100? Does anyone know if they even exist for the bike? Would love to see some pics. I think they would be a good looking farkle to match the engine!

I posed this same question a while back and got no response. Searching the net I have not found any reference to finned collars. Too bad as that would be a nice looking farkle.

The collars on the new Bonnies look very sharp.
