Hi, I bought a 2005 Road King Custom and she came equipped with Hooker Header slip ons. They are not at all loud (which I am used to having) I was going to get some V & H, but, saw where they are adjustable baffles to accomodate the sound. Which way do I turn the baffles. I did unscrew the two screws and removed the end piece all together because the baffles seemed to be stuck. Is anyone else have this issue or know how to help me out with some info? Thank you boys.
