Catalytic Converters

In 1993, Catalytic Converters became a legality in the UK as part of the Euro Emissions standards. The aim of them is to improve air quality. As emissions standards have become more stringent the number of cats on a vehicle has increased. Many vehicles now have two or more to enable them to meet the Euro Emissions standards.

We produce Europe’s widest range of catalytic converters including:

A Catalytic Converter (Cat) is an emissions control device that reduces the level of harmful gasses that enter the atmosphere. It works by converting the harmful exhaust emissions into less harmful ones when the gasses pass through it.

Different Styles of Cat

Underfloor Cat

This type of cat is positioned directly on the underfloor of the vehicle.

Manifold or Close Coupled Cat

Designed to fit directly to the vehicles manifold where the exhausts gasses are hotter.

Maniverter

The cat is part of the manifold and is therefore positioned where the exhausts gasses are at their hottest.

Common Cat Faults

There are several reasons a cat can fail that are not the fault of the cat itself:

  • Impact Damage
  • Melted Monolith
  • Use of exhaust paste
  • Plugged/Contaminated
  • Poor Fitting
  • Engine Management Light
  • Emissions Failure
