04 fat boy, 95 kit, httc non ported heads, forged domed pistons, 211 cams, 42 mikuni, s/ air w/k&n filter, 16 guage double barrels. Had all work done new, never happy w/exhaust, believe it is too restrictive. Runs smooth w/no glitches, but know I can do better. Prefer something that works best in 2-4k rpm range.Narrowed down as follows: 2-1: pro pipe or road rage ( also could think fat cat, but can't believe how heavy system is). 2-2( original python 3 or khrome werks ar III, or stock head pipes from softtail standard with s&s performance mufflers or rush slip ons. Can live w/looks and sound of any included. Don't like tinny sound, more into deep rumble sound. Any input appreciated.
