hi, macs 15cc nitro pipe with can on back, macs 15cc quiet pipe. lots of pipes to choose from. i would start with a 1667 octura prop.

Tom,

I would try a CMB 67/80 quiet pipe set at 11 1/2" and a stock Octura H667 prop.

Im currently running an old AB parabolic pipe@ around 12in and a 1667 that has been cutback and cupped up abit.

seems to be fairly competive.
