I have little bit of both and love it. I can let you hear it in person since I live right up the road from you in Anderson SC.
Viking Exhaust header leading into a SuperTrapp muffler with proper tune. I prefer no discs at all
I have discs to tune the sound but it just sounds better with no discs. Very deep exhaust tone. Sometimes I leave the end cap off and ride without it. It's not staggering loud like you expect at idle but when you give it the beans she gets loud.
