It's all about personal tastes IMO.
We have some people running most of the combos you are all talking about.
Personally, my 2 "main riders" are totally different.
My 103 is pretty tame for the long rides. I'm using the x-pipe and 1 3/4 cvo cores because I ride 2000-3000 RPM all day long, and I like the quiet.
My 113 is more performance minded (but, a SG) and I'm running true duals with more open mufflers. It is pretty loud under load and over 2500 RPM, but we don't do the long rides on that one!
I like 'em both for different reasons.
Our group also has different combos of pipes/mufflers and I have my favorites. The owners (some of them) change mufflers like I change my socks (that would be once a month!
)
Different strokes and pipes for different..........you get the picture!
Run along with your buddies, see what you like best. Hard to tell the difference in "seat of the pants dyno" when just riding!
Of course.........JMHO
