Well I am the kind of guy that wants to know "why". I was told to run SB and why but i am the curious type to wanna run BB. Just because I like to know what will happen. Although I am happy at the way the bike performs with the SB. And I am convinced that the SB pipes are optimal for my engine setup. But theres always that doubt that "what if". So that "what if" is what im interested in. Carry on!
