The “catalytic converter,” also known as a “catalyzer,” is a crucial component of a car. A lot of toxic substances will be generated in exhaust gases and cleaning them will be necessary.

The catalytic converter is designed to transform toxic substances into harmless substances through chemical reactions. To keep the earth in a green environment, the process is always an important part of a car.

Even though the number and location of catalytic converters are different in each car, they are generally installed between the engine and the exhaust.

Inside the catalytic converter, there is a honeycomb-like structure called a “honeycomb.” It is coated with precious metals to transform toxic substances into harmless substances through chemical reactions.

For example, the GR86 OEM is equipped with an OEM 600-cells catalytic converter. However, HKS catalytic converter has successfully reduced it to 150 cells, which is a quarter of the OEM specification. The design reduces exhaust resistance while also improving power, torque, and response.

A high-quality catalytic converter is not designed solely by reducing the number of cells to increase car performance, as this could reduce purification performance.

HKS uses a honeycomb structure that optimizes the composition of precious metal components to ensure purification performance. In addition, we have in-house equipment that can perform tests equivalent to public emission tests. Therefore, we can fine-tune the specifications until we are satisfied, clearing the emission tests while improving performance.

The HKS metal catalyzer series has passed the strict Japanese emissions regulations and has been issued the emissions test certificates. You can enjoy improved performance without worrying about causing environmental pollution.
