Well, I did...but more so in a helpful way.
But in any event, and if that's the case, my apologies. I actually knew that answer, as I too had called Tischer BMW to ask and told the same thing. I just didn't want you to be mislead by hearsay or guessing here on the site, as happens more than not. So a call would have been the most prudent course of action in this case.
So I too am interested and if you proceed w/ the 'IS muffler system, let me know if it works out.
