Aaron,

Could you post a pic of the RS 21 Pipe, I assume it is made for a rear exhaust (wrap around header) or is it long enough to be used on a front exhaust (Valvola, Mac) style engine

i run the new 5 port nova and cooper pipe with the single exaust hole & 440/3 octura prop my boat is real fast . and it didnt cost a arm and a leg . im very imperssed with the nova 5 port and it only cost around $215.00 with header $250.00

Glenn Quarles on here also sells the NR motors direct. He is in the MFG Forsale forum. Do you want a 180 header motor, or a valvola style? I see from your signature that you have several 20 monos. Which go you prefer the best?

See link below for more CF pipes that I produce here in the USA. Now available from .12-.45 sizes. Also both 180 header, and straight header styles.

Squarewave Pipes

OK, I gotta ask, Why are you tossing the Rossi? Is it one of those with the oval cooling head?

If it is, I had one in our Speedmaster 21 and it hauled. The secrets were that it takes a loooooong time to break it in. It likes the pipe on the long side also but spun a Prather 220 with no sweat.

here is the pic of the engine
