On the subject of the pipe, I think it would be a great addition, and if it really performs, well worth the $$$ and someone will come up with a bigger gas tank to match it, or Waterdawg's will work already (as long as he will produce/ship them in a timely manner).
But what about when agressive riders (not me) sub under? Would the gas tanks inlet allow water into the tank? What about when you flip? Would it starve the engine and cause lean conditions?
Dont take it as bashing, these are just my first thoughts
