I hear ya about the pipe(s) and the power they make. I have a S7II in my buggy now, and before i was just using the dinky stocker pipe that it came with. Well, I went and got the RB pipe suitably rated for this engine(per a tech at rb service facility), and got the one he reccomended, and i couldnt not believe the difference in power once i switched. Ive only got a little over a gallon so far on my s7II, and every time I run it, it just seems to keep on getting stronger and stronger. I like this engine and pipe quite a bit.
