HKS Stainless Steel Exhaust Manifold

• 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.

There were many famous turbines in HKS' History. And that's the history of the tuning itself. HKS have been optimizing those turbines for each automobile and with other necessary parts they made tuning kits for small tune-ups to super high-power tune-ups. HKS' turbine kit can fulfill your desire of tune-ups.

HKS turbine kits are developed under the tough situation such as street or motor sport competition. We have tested in all situation of driving environment and collected the data. All these exploitation lead them to develop the world's best tuning turbine kit.
