I have a 08 street glide. Rinehart True Duals, sert and download. I have changed the baffles a couple times. Now staying sith the Big City Thunder Baffles. Love them! deep and loud. My bike runs great. What does a dyno do? Is it just a measurement? Is it a tune with the Sert to make sure everything is adjusted and running right?
