They are road legal cans. Plus, BMW offers the Akra as OE. Unless you remove the baffle (which you can’t anyway) I can’t see how a legal can could effect the throttle response.Aside from the noise, I am concerned that the SC or Akropovic slip-on could make the throttle less smooth than stock, which I consider to be very smooth, even in dynamic mode. I wouldn’t want to sacrifice that. I’ve read that torque delivery shifts to higher rpm. Anything to that?
Coming from a bike with perfectly jetted and set up carbs, I was surprised how good the throttle response was on the BMW. It is perfect. The only thing I had to get used to was that slight on/off effect at junctions etc.
