Your Lexus GS300 catalytic converter has an important job to do, but unfortunately this component is often misunderstood. Though the name and the price tag makes the catalytic converter seem terribly complicated, this essential part of your vehicle’s exhaust system is actually a filter, albeit a highly specialized one. You may be wondering why a filter costs so much money to replace, and the answer lies embedded in the walls of your GS300 catalytic converter.

Since its job is to filter exhaust gases, your catalytic converter cannot use paper fibers to remove contaminants, like your oil filter and your air filter. Therefore, the Lexus GS300 catalytic converter contains small amounts of precious metals, usually platinum, palladium, and rhodium, to create a chemical reaction with the exhaust gases passing through your system.

When harmful substances like carbon monoxide, hydrocarbons, and nitrogen oxide pass through your GS300 catalytic converter, the metals contained in the filter act as catalysts to smash apart the molecules of the pollutants, which are then re-formed into carbon dioxide, nitrogen, and water vapor. Unfortunately, the drawback to this special function is that it can be difficult to tell when your Lexus GS300 catalytic converter is not working right.

Some of the symptoms of a faulty catalytic converter include sluggish performance, decreased fuel efficiency, and a foul-smelling exhaust, but problems with your catalytic converter are usually detected during an emissions test or when you are having other exhaust work done.
