I have a 15 with extreme power duals Vance and Hines and rhinehearts 4" mufflers. I am not real happy with the sound. Was hoping for a little louder sound. Anyone have any idea what I could do. I know removing the baffles but I think that would sound to crappy. Was wondering if these mufflers had wraps on the baffles and how it would sound if I removed the wrap? Any idea ?
