Frequently Asked Questions Ask APW
How often should the catalytic converter on a Toyota Camry be checked?
Answer: It should be checked at every oil change. This is the best time to have the Camry's catalytic converter inspected thoroughly for damage or wear. Converters should only be replaced when necessary, but they should be maintained regularly to keep them in good shape. To prevent converter failure, use only the right grade fuel that is specifically formulated for Toyota Camry. This will improve the vehicle's performance and reduce harmful exhaust emissions. Be careful in using fuel, transmission, and engine additives because these substances can potentially deal damage to the Camry's catalytic converter and oxygen sensors.
What's the difference between a stock Toyota Camry catalytic converter and a high-flow catalytic converter?
Answer: Some stock catalytic converters of Toyota Camry models are not suitable for high-performance engines. If the vehicle has a modified engine and exhaust system, the catalytic converter must be upgraded to a high-flow unit as well to match the vehicle's overall power output. Before upgrading the catalytic converter, check the local emission laws first to avoid violations. In some states, stock catalytic converters should only be replaced if they get damaged. When upgrading the catalytic converter to a high-flow unit, make sure the inlet and the outlet size matches the size of the exhaust pipes for maximum power and airflow.
Will a modified exhaust system damage the catalytic converter?
Answer: Most people install a high-performance exhaust system in their engine without considering its effect on the other parts. Restricting the flow of exhaust can damage the catalytic converter. In some cases, the converter will fail to operate completely if it's not compatible with the new exhaust system. Changing the size of the exhaust tip to a smaller or larger unit can have negative effects on the catalytic converter as well.
