In my search for a Li/Re ESD for frontlers with enough exhaust gas and sound from the right end tube I have also been pushed again on Projekt Zwo.http://www.projektzwo.com/…/fzg.php?… Only 675 EUR, a nice look and, the big advantage: The right end tube is fed from the ESD, not as a pup solution as with Eisenmann The only disadvantage is that the right end tube is shorter than the left. Have a bit of worry that you can see it?! I asked for two pictures of them at Projekt Zwo and got two pictures of them. I also include here. THE GREAT QUESTION: how does this thing sound??? Does one know? @TTWorld: is the interesting for you?
