HKS: METAL CATALYZER - Yaris GR

Metal catalytic converter has lower exhaust resistance and higher durability by using a low-density metal cell as opposed to the stock ceramic catalyst with a high density cell.
Both the first and second catalytic converter have 150-cell metal core, which significantly reduces exhaust resistance.
The catalytic converter has minimum size cell with an optimized ratio of precious metals to ensure both purification performance and exhaust pressure reduction, and has obtained an exhaust gas certificate from a third-party organization in Japan.
The first catalytic converter can be fitted with a stock heat shield to prevent heat damage*.
The pipe diameter is enlarged to D75mm (compared to the stock D70mm).
Buffed and polished, all welding was done by TIG welding for best aesthetic appearance.
