how can a 600 hp v8 be compared to a 25 hp single cylinder motor .just the amount of flow required to make that motor run is probably enough to suck start a harley. it needs the most free flowing exaust out there, but dont think because there's no "muffler" that there is no back pressure in the pipes, thier bent and cut to whatever length for that . if the had monster blowers they could run 2 foot pipes. after that much hp exhaust no longer matters so long as it gets the heat away from the motor and flows as much as it takes in.
