Owned the system on an e60 v10 many years ago. It was louder than absolutely anything at the time. Sounded great back then, but a bit too loud for my my tastes these days. I remember the jig was a little bit off and we had to bend the pipes where it tied back into the system due to tolerances. Besides that hiccup, fit and finish of the cans and tips was second to none.
Everyone and their mom would nag me that something was stuck in my tips though.
I remember a bunch of drama between Meisterschaft and Eisenmann. Not sure if partners split or one copied the other, but both systems are on a whole different level of craftsmanship compared to the American stuff. (The internet gangsters were trying to point out the flaws between the two companies and not much if anything could be pointed out about Meisterschaft)
I know, not much help related to our platform though but it is something to go off of. I had the sport (gts I think) cans vs the touring. I think touring is the gtc now.
