Exhaust system
  • 2-into-1 system contributes to the Ninja 250RĂ¢ € ™ s low-and mid-range torque and smooth, step-free power curve
  • Slightly upswept silencer extensively tested to determine chamber size, connecting pipe length and diameter to achieve least noise and most power
  • Meets strict emissions with dual catalyzers; one in the collector pipe and the other in the silencer
  • Using two catalyzers minimizes the power loss
  • Positioning the first catalyzer as close to the exhaust ports maximizes its
