Arrow 3 into 1 power gain?

[wingedwraith]

Hi all,

Does anyone know what increase in power the Arrow three-into-one exhaust gives with the Arrow map used?

Cheers

Neil

I don't have a before and after, but my bike puts out 128 rwhp. I've seen some sites claiming it gains from 3-6 rwhp.

Most stock dynos I've seen give around 115 rwhp, the one arrow 3 into 1 dyno I've seen gave 128 rwhp and 113nm max torque.

I let a friend with a stock speedy take mine out for a test ride a couple of days ago...he said the difference in power was massive! Getting the arrow system is his top priority these days.

With the stock cans Speedy is a wheelie machine...with the Arrow system it's a wheelie machine deluxe.

Another quite important point is that the Arrow system moves the max torque up the powerband to around 7-7500 rpms.
