After I put the quiet tip on the FSW muff my riding buds said we ought to be able to ride together now without getting arrested! No appreciable deterioration in performance and it's a little quieter....I liked the old sound, but now everybody's happy. FWIW

 

You got a photo of that pipe? I think that is one of the few that I haven't seen installed on the bike.

 

I'll post a photo after I get it out from under the thrust melted fender...no kidding...the fit was a little off...but it sounded great!
