I put a P1X supprssor on my 2 Brothers M2 series and thought it might be causing to much back pressure at cruising speeds. It helped temendously on the low end and mid range though and I definately use that a lot more than setting the cruise at 85-90. Anyone who has the m2 series I would highly recommend the P1X.

I cruise at 35-40mph on my F4i in 4th gear so around 4k. Occasionally I'll have it in 3rd for a little more oomph or when there's a light coming up and it's pointless to shift up just to shift back down. I run the same gear/rpms on my little Ninja 500 as well since it's below 6000 rpm performance is nearly identical to the F4i.
