true some extent as I understand it. a twin will inherently not scavenge as well or as evenly as a four, but I belive that is why your premium kits like Sato and Akrapovic use different sized pipe on one side. in order to increase the velocity a tad and make the rear cylinder "suck" for a slightly longer period of time. I digress though my twin tuning is pretty limited.
