yoshimura vs white bros.

[jokerman_28]

i am debating on wich pipe to get for my 400ex. should i go with the White Bros. Pro Meg complete system ($420) or the Yoshimura Comp series full system ($430) or Yoshimura Pro Series titanium full system ($640) or Duncan Racing Fat Boy 4 complete system ($550)

White Brothers IMO!

WB or Duncan, I've only heard about low gains with the Yoshi. Although it looks nice. Everyone seems to use "Sparks Exhaust" to compare power too. WB E series is very close to Sparks out put.
