Yashio Factory Exhaust Manifold

By using 3.5mm thick SUS304 stainless steel and narrowing the inner diameter of the cylinders to increase flow velocity, we succeeded in improving the response of our exhaust manifold at both low rpm and high rpm. As the torque is considerably higher than our previous model, it is the strongest exhaust manifold we have made to date.
