Grump, that is exactly what I am looking for, bang for the buck. I do not want to spend money, time and aggrivation installing Unifiler's and rejetting when people have had mixed results at best with this type of performance enhancement. Phil, I do hear what you are saying about all
pipes will increase HP and therefore see were choice comes in. Thunderbike pipes claim an increase of 28% or so. My thought is there is not much left in our bikes after that to improve. Would that be a correct statement?
