Basic Tips for Buying a Replacement Toyota Catalytic Converter

If you have an older Toyota thas has remained untouched in the exhaust system department and you need to pass an emission test, you need to check whether your catalytic converter is still sound and operating at optimum capacity. Catalytic converters are one of the most underrated parts as thanks to them, we’re all alive and well, especially those of us living in large cities. The purpose of the catalytic converter is to eliminate the harmful pollutants coming out of your engine and turn them into less harmful pollutants before releasing them into the atmosphere.


That being said, when buying a Toyota catalytic converter, you need to make a well-informed decision. There are two basic types of catalytic converters: 2-way and 3-way converters. 2-way cats are used on diesel engines and they perform 2 important functions – reduce the excess of carbon monoxide and hydrocarbon. They do this by oxidating the carbon monoxide and converting it to carbon dioxide and oxidizing the hydrocarbons and reducing them to water and carbon dioxide. 3-way converters perform one more function – they control the emission of nitrous oxide, which is a potent greenhouse gas. They reduce the nitrogen oxides into oxygen and nitrogen.

Next, you have to consider the type of fit of the Toyota catalytic converter. You can choose between direct-fit and universal-fit converters. Direct-fit cats are designed to simply bolt onto your existing application without performing additional modifications to your vehicle. This is the recommended option for people who have a stock exhaust system and want to ensure a proper fit. Universal-fit cats, on the other hand, oftentimes require some welding and fabrications to ensure a proper fit. This style offers more choices, but you need to confirm your application before buying one. Universal-fit catalytic converters are recommended if your Toyota already has one, or if you’re looking for a more cost-effective solution.


Regardless of what type of converter you end up buying, you should take into account that labour and part costs can vary greatly. This all depends on the type of your Toyota, who ends up installing the new cat, and what style you choose. You should look to buy a cat online, as its generally cheaper and you have more options to chose from. If you’re looking to save money, buy a universal-fit cat that has your type of Toyota on the list of vehicles it fits, otherwise, the labour to install it may make it more expensive than a direct-fit.
