Universal catalytic converters are categorized based on emission Euro norms and engine displacement or power.
They cover EURO2, EURO3, EURO4, EURO5, and EURO6 emission standards, with engine displacements ranging from 800cc to 5,000cc.
When choosing a universal catalytic converter, it's crucial to find the emission norm data for the vehicle in its registration document.
Most original equipment manufacturers use ceramic catalytic converters initially, which are suitable for new engines with low mileage.
Metallic catalytic converters have a metal core and functionally they are equivalent to ceramic ones, but they are structurally much stronger and therefore more durable.
When replacing catalytic converters in vehicles equipped with LPG systems, it is recommended to use a metal catalytic converter.
