Gener, I have talked to my race partner about the pro pipes, he and his son are both gonna use them on there MAC OB's ( they seem to work pretty well on them), Weve got three in our pool, one on each boat and one for a spare in case of a mishap. We pool all of our stuff together, and they dont really want to get rid of them now that they have made them work. ( I still have not had any good luck with the pro pipes....)
However, I read somewhere that your rossi might want a small volume pipe? I have the smallest volume outboard pipe ive ever used, and it doesnt work all that great on my Novarossi. (killer on a K&B though) Heres a pic of the pipes I have recently made and a certain carbon fiber pipe that I recently scored....
