Why Choose a High Flow Catalytic Converter?

A high flow catalytic converter helps balance emissions compliance, durability and exhaust performance. Compared with worn or partially blocked factory converters, a quality high-flow design can improve exhaust efficiency and support better overall flow through the system. This makes it a strong option for replacement exhaust systems, street-performance upgrades and custom exhaust fabrication.

Frequently Asked Questions

Is this catalytic converter a direct replacement?
It is designed to suit Holden Commodore VN–VS V6 and V8 applications, but exhaust systems can vary. Please check your pipe size, mounting arrangement and available space before ordering.

Will this catalytic converter fit a VS v6?
No, this only fit VS V8 Models

What does 100 CPI mean?
100 CPI refers to the cell density of the metallic substrate. A lower CPI high-flow design generally allows exhaust gases to pass through more freely than more restrictive factory-style converters.

Is this suitable for street use?
This converter is built to Euro 2 standard, but vehicle compliance requirements can vary by state and application. Always confirm local emissions and registration rules before installation.

Are fitting parts included?
Yes. Gaskets and bolts are included with this catalytic converter.
