The V&H Pro Pipe gives excellent performance but probably not much of an increase in power & torque over your current setup. It's important to consider that the specs of the stock cam will only allow a certain level of performance in your engine no matter how many speed parts are bolted on.
I truly like the way my setup is now as dual pipes flowing from engine to rear of the bike, clean look, V&H Pro-pipe is also very clean look, except one pipe.
If not much HP gain then I will not bother with it and leave my setup alone, I will find a friend of mine that is good in tuning sportbikes but he is good in Dyno tuning so maybe he can push maximum power out of the setup I have as I am not getting help (being ignored by FP3 tech support, sent 2 emails and left a voicemail msg) from V&H FP3 support group. That's one thing I can't stand about some of these companies, they won't do much or totally ignores you when they can't help, instead of at least try or just straight out tell me that's all that can be done. Oh well, live & learn, never again buy V&H product, I will spend a bit more money if I have to and go with Dirty Bird 2-1 exhaust if I upgrade cam in the future and get more HP out of my bike.....or save up and move up to 120 cu in. motor......in the meantime I will just live with my setup and enjoy the ride.....
