evolution v slipons

well a little suprised today as my bike was run on the dyno with the evo system for the first time, before today we've been running the slip ons.
the vedict is what a waste of money no gains anywhere.

not even weight?

not that i'm considering the evo system, i was enamoured by it at the beginning but the money is just too much...

not very good news for the people who have already fitted the evo's

sure your saving some weight and they are tucked in a bit more but i for one thought you might gain a bit more in the hp stakes.

agreed. 2700euros for the same power as my 1000euro slip ons.... hmmm
i'll have the slip ons thank you very much

have you seen any dyno runs?

we're getting 132 rwhp with head work, dialled in cams and slip ons.
