for 2009 kawi has come up with a innovative low tech way to get the effects of a variable intake system like the one the R6 uses. basically they have made a combined velocity stack funnel that draws from the long part at low speed and the shorter stack at high rpm. anywho, after seeing the above image i started poking around through the OEM parts catalogs on bikebandit and it looks like the previous generation bikes can fit these funnels as well. might be good for a modest bump in mid and top end power since the 07 08's used the standard two short two long setup.
