I just had my first service done on my 2010 road King, and went ahead and had supertrapp slip ons a big sucker and a power comander instaled as well. I can see the baffles in the slip ons and it looks like they are just held in by the end cap screws, can I pull those baffles with out a big power issue. Also how do I lower the idle to get the famous "potato potato potato ....BBBLLLAAATT sound?
