Yes I do know this.
Reason I suggested the BZM and Zocchi pipes, they are optimized and purpose built for polini motors (6.2+ polini motors), which is what the banshee is based out of. You don't really think the chinese "designed" a totally new motor do you?
The BZM and Zocchi race pipes extract more hp than any other race pipe out there for the polini motors. For easy bolt on purposes, changing out a pipe on on a polini motor'd bike for a BZM or Zocchi pipe, yields at least a 1-2HP gain.
Again, since the banshee is based out of the 5 port, 50cc polini motor, I would assume, adding a BZM or Zocchi race pipe will add at least a hp or two. I never said I guarantee'd it would yield additional hp. I'm only basing it on my experience on seeing other racers get great results with the BZM and Zocchi race pipes on their bikes.

The calculations for the design are complex because the pipe has to be matched to the engine. Even if you want to use trial and error to tweak it after the primary design is done and constructed you still have to get the first step, design to the engine, done first. The pipe sections are: Header, Belly, Convergent Cone, Stinger. To see the sections and calculations click the attachement. |
