I had harley install screaming eagle pipes and a stage one download. I put on the larger air filter It runs fine but it never really put the sound out I had hoped for I rode for a year but finally gave in a bought a set of Reinhart pipes. They sound good but perhaps a little too loud ( hard to find the middle). Now the hard part Many site blogger's say fuel management is needed even though I had a stage one, but they also maintain i dont need the dyno tune. I am on the fence. It cost a lot. Opinions?
