Just wanted to say hello to fellow Star owners. I just got my 07 Roadliner 1900 s with 2400 miles on it and already got my new HK3" big straights along with a Cobra F2000 computer sitting in the garage. I checked the forums before I joined to get some clues on exhaust change out. I have questions on the EXUP valve if I need to remove or keep and hopefully a diagram on the removal of the old exhaust if I even need one. I want to do this right so any help or suggestions is a plus. I look foward to the forums. Thanks.
