Hi eveyone,I have the DNA stage 1 and 2 filter on my xt660z. I also have an akrapovic single can and a power commander V with a custom map for this setup.
I am considering getting a DNA stage 3 filter, I think I would need a new map for the PCV to allow for the stage 3 but would appreciate your opinions?
Also, would the stage 3 make the bike even more loud than it is with the Akra single can. I have blocked off the AIS to minimise the back fires!

Many thanks.
Neil
