According to the Cycle Shack website the slip fit mufflers fit 06 Dynas.
I currently have a S.E. Air cleaner and S.E. High Torque mufflers and a stage 1 burn on the ECM on my 06 Bob. I prefer the look of the tapered mufflers, but they don´t sound as good as I´d like them to.
Does anyone know whether the stage 1 burn is good enough for the Cycle Shack mufflers? I´m guessing yes, because it works with the S.E.II mufflers.
