I need some help real quick. can any one tell me the real diffreance between the akrapovic full race system and the full evolution system. other than the evo is more money. This is kind of a general question cause the system will not be for a 14 but rather a new 08 cbr which i am buying for a second bike. The 14 wil never have another pipe other than the alien head. but alas Brock doesn't make a pipe for the honda so I am torn and looking at the akro. thanks guys
