Description

Developed at the same time as the Super Sound Master and exhaust manifold.
By installing the HKS metal catalytic converter on the S2000, which has high potential, you can improve the output after switching to the high-speed cam, creating a more exhilarating car.
Furthermore, by installing the exhaust manifold and Super Sound Master as a set, you can get an overall well-balanced power feel.

The number of cells in the stock catalyst is approximately 400 cpsi, while the HKS metal catalyzer uses 150 cpsi. It has achieved a high level of exhaust gas purification performance while significantly reducing pressure loss.
It is particularly effective in reducing pressure loss in the high rotation range, providing a sharper engine feeling.

You can see that the exhaust manifold (pink line) has an advantage in the low and medium rotation range, and the catalytic converter (blue line) has an advantage in the medium and high rotation range. Combining these two (yellow line) will be effective across the entire range.
