:P Hello chaps and laydeees. Having some gasflowing work done soon. Was wondering what improvments and gains others have seen if they had before and after runs done etc. My 54mm system is dying to breath at the top end you can see on the graphs where it just sort of goes limp, doesn't tail off but just levels off the rest of the way to the limiter. Plus comparing figures with other 853 owners running different exhausts but all having blueprinted or flowed engines this appears to be the only reason for the power deficit. opinions welcome.
all money no sense
