This product has been developed in response to considerable demand for a balance between peak power and torque. In its development, we at Spoon have implemented all possible combination's of pipe diameter, assembly rotation, and other similar factors in exhaustive engine-bench, flow-bench, and actual-driving tests. Accordingly, power and torque were successfully balanced, and by both including a bulge in the assembly-collector section and using slightly uneven lengths for pipes, it was possible to achieve our ultimate target or reduced weight. Furthermore, with any reduction in low speed torque, the discharge of gas was carried out forcibly from the exhaust port in the high speed range, and the results of this showed that it has also been possible to achieve increased replenishment efficiency for the combustion chambers. In other words, we have been successful in the development of an exhaust manifold with a real increase power. It can equip with the OEM exhaust pipe.
The spoon formed the silencer in a part for the central part of Exhaust Pipe-B. Moreover, the optimum exhaust flux was designed and produced commercially.

By using numerical control machining to achieve a large, 4mm opening for the throttle, the flow-pass area is increased by 16% and the inertial mass during the intake of air is reduced. Accordingly, peak power is increased by a factor of approximately 6 horsepower.
