hi all

having probs with my DL 50 & KS 1060 tuned pipe (vess 23b prop) being to peaky/ punchy, ive measured the header lengh (TBM 25mm drop) from the exhaust flange to start of pipe and it comes out at 12 1/4 inches now i ve read somewhere that it should be 11 inch with this pipe but my problem is i have a nice knuckle on the end of the header which i dont really want to cut off so my question is do i have to cut it off or can i shorten the pipe lengh and by how much ??

cheers guys [sm=spinnyeyes.gif]
