Each disc allows a specific amount of flow through the muffler. adding discs increases flow for high end Hp. Fewer discs decreases flow contributing to low end torque. Super tramp recommends 4 disc on a stock motor in the 150 cc range for good pull. My kit came with 12 discs so some number between would be the magic number for my setup.
