■Features

  • Stock replacement type stainless steel exhaust manifold is now correspond with new F model.
  • We have adopted ideal pipe diameter by eliminating the flange step which is the reason for the resistance.
  • In order not to drop the flow rate we made the shape of junction portion for little change of the cross-sectional area to the set.
  • With our test drive and vibration test resulted to disuse the flexible tube and slip joint which causes the exhaust resistance, and reinforced for junction portion.
  • For these changes, both of the power and torque has increased at the all range. It's much better to control at low to mid RPM.
