Scored a new/unused akrapovic slip on for my v2 from a private individual overseas. Problem is the akra dealer map doesnt cross overseas so its not coming out with my local dealer. Looking at the t800 as an easy alternative. T800 said the SBK map would work. My worry is that the akra is a dual exit slip on. Isnt that going to be highly inefficient or something? Anyone with experience done this?
