the shorter the pipe, the higher in the rpm scale it assists.

9000 rpm would mean a primary pipe length close to 660mm.

My engine builder recommended 38mm(1.5") primaries that are 710(28") long. Collector to be 60mm. My engine has peak power @ 8300rpm. I do NOT as yet know if it should be a tapered collector or some other type
