The exhaust manifold that pull potential power out of turbo vehicle. 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.
