Catalytic converter ‘dos’ and ‘dont’s’

As one of the world’s major suppliers of complete exhaust systems, Bosal say that the catalytic converter is one of the most important parts of a vehicle’s emissions control system, preventing harmful exhaust pollutants from entering the atmosphere by converting them into water vapour and less harmful gases.

What you should always do:

• Check the cause of failure of the original catalytic converter and rectify the problem before fitting a new cat.
• Check the condition of the lambda sensor and replace if required.
• Use new fittings compatible with the replacement catalytic converter.
• Ensure a fully gas tight exhaust seal.

What you should never do:

• Assume that a replacement catalytic converter will cure a fault. For example, overheating is an indication of a fault before the catalytic converter.
• Use exhaust sealant anywhere on or in front of the catalytic converter. Using exhaust sealant will void the catalytic converter warranty.
• Use undue force when fitting.
• Subject the catalytic converter to any impact forces.
