Quiet muffs??

[M!ch@el]

i have an 07 classic and i like the fact that it is quiet but i want the performance of a dual system so can anybody give me an idea on the most quietest catback

That is a tough one cause most want the opposite when it comes to exhaust I looked up dual exhaust for a thread awhile back and there was a write up on how to get the same flow but keep it quiet maybe it might be useful to you here is the link
