SB 17- FH on one of them and SB18 FH on the other one. Those are Hatori mufflers.

Thanks David Ive heard of hatori but wasn't sure what people are running. You must be happy with the pipes. Do you notice a difference between the two pipes?

The SB18 allows a little bit higher RPM on the rotor head.

Thanks David, I did notice on heli proz that one of the pipes was for the c-spec and the other was very similar. It sounds like either pipe along with the os motor is going to give me more than enough power.
