Highwayman Pipe Tuning: exemplified for the Yamaha TD3 250cc twin

Representative

Achieving a specific tuning goal with pipe design.  The goal was to achieve equal or greater power while moving  the red-line from ~13,000 RPM to a max of 11,000 RPM. The pipes on the bike kept wanting to pull way past 11000 RPM, and the owner wanted to keep the power below that to preserve crankshaft life, while not loosing race winning power!
