Akrapovic 2-1 syste, end cap?
I have just got hold of a durbahn modded Akra system (http://www.honda-rc51.de/Acra%20mod%...20yourself.htm
). In my opinion the outlet seems a little on the small side when there is only one pipe. Does any of you have experience with this? Should I get a new/modify the end cap with a bigger outlet or will the power delivery not be affected? I don't have the exact measurements here atm, but I can find out for tomorrow.
The engine is stock, only the pair/flapper-mod and a durbah airbox with a pcIII installed.
btw, the weight of the complete system is 3,8kg (8,4lbs)
