Why choose a 300 cell converter over a 200 cell unit?
A 300 cell converter provides slightly more surface area for the chemical catalyst reaction to occur. This often makes it more effective at preventing "Check Engine" lights (CEL) on modern ECU systems and reduces the raw fuel smell (exhaust fumes) better than a 200 cell unit, while still flowing much better than a standard factory cat.
Is a metallic core better than a ceramic core?
Yes, for performance use. Metallic substrates are much thinner than ceramic walls, allowing for more open space and better airflow. They are also significantly more durable and can withstand the higher temperatures and vibrations found in modified or turbocharged engines.
Are these 300 cell converters legal for road use?
In Australia, any aftermarket converter must technically meet or exceed the emission standards of the vehicle's original equipment. These 300 cell units are designed to provide high-flow performance while helping vehicles meet Euro 2 requirements. Always check your local state's specific registration and engineering requirements.
Do I need to weld these in?
Most of the 300 cell converters in our collection are universal fitment, meaning they have a "barrel" shape and require professional welding to be integrated into your exhaust piping. This ensures a leak-free, custom fit for any vehicle make or model.
