Is Aftermarket Catalytic Converter Effective?

[SkylarMarie]

Replacing with an aftermarket catalytic converter is not effective. The specific hazards of aftermarket catalytic converters are as follows: 1. Prone to damage: The operating temperature of a catalytic converter typically should not exceed 800°C. However, if a cylinder in the engine misfires, excessive unburned fuel gases will be present in the exhaust. These gases may ignite in the exhaust manifold, causing the catalytic converter to fail or be damaged due to excessively high temperatures. 2. Environmental pollution: Aftermarket catalytic converters have poor exhaust purification efficiency, which not only causes significant pollution and harm to the environment and human health but also leads to deposits on the active surfaces of the oxygen sensor and catalytic converter within the catalytic converter. This can result in 'lead poisoning' of the oxygen sensor and a substantial decrease in the purification efficiency of the catalytic converter, eventually leading to its failure.
