Catalytic converters – standard and sport

At Select Parts you will find catalytic converters for cars, including standard replacements for the exhaust system and sport high-flow catalytic converters for cars with a modified exhaust.

A catalytic converter reduces the amount of harmful substances in exhaust gases. When choosing one, pipe diameter, dimensions, converter type and compatibility with your car and exhaust system matter.

Standard vs. sport catalytic converter

A standard converter is meant to replace an original or damaged one for normal daily use.

A sport converter is designed for freer exhaust flow and lower back pressure. That is why high-flow cats are often used with tuned exhaust systems, downpipes and higher-power cars.

How to choose the right converter

Before buying, check:

  • inlet and outlet diameter;
  • overall dimensions and available mounting space;
  • the type of exhaust system;
  • whether you need a standard or a sport high-flow converter;
  • the requirements of your specific car.

With universal converters, installation may require adapting or welding to the exhaust system.

Sport high-flow catalytic converters

On tuned cars, freer exhaust flow can be an important part of the full setup. Sport converters are a good fit when you want less flow restriction without removing the catalytic converter altogether. Pair them with a downpipe or a performance exhaust system.

Catalytic converter FAQ

What is the difference between a standard and a sport catalytic converter?

A standard converter is mainly meant for daily use and for replacing the original converter. A sport high-flow converter is designed for freer passage of exhaust gases and is often used on modified exhaust systems.

What is a high-flow catalytic converter?

High flow is a sport catalytic converter whose construction restricts exhaust gas flow less than standard solutions.

How do I choose the right catalytic converter for my car?

Check the inlet and outlet diameter, dimensions, the type of exhaust system and compatibility with the car. Universal converters may need adapting during installation.

Which catalytic converter diameter should I choose?

The diameter must match the car's exhaust system. On a tuned exhaust, the diameter of the other components must be taken into account too. If you are unsure, Select Parts can help you choose.

Is a universal catalytic converter suitable for every car?

No. Universal means the converter is not made for one specific model only. Check the diameter, dimensions, installation method and your car's requirements.

Can a sport catalytic converter be used with a downpipe?

Yes. A sport converter can be part of a modified exhaust system with a downpipe, provided the sizes and configuration of the components are compatible.
