Interesting questions and replies. Good that someone did that. I would have loved to go that event, but unfortunately it seemed really hard to get in there.
In the end, it is nice to hear these things that are now confirmed and we assumed before. On the subject of the exhaust, I heard that Akrapovic might be working on an exhaust for the M2, so there is hope. Else just fit a Hamann exhaust with down pipe and it sounds like racing car. Which means load enough
