1 Answers
The difference between OEM and aftermarket catalytic converters depends on the specific product in question. It is not necessarily true that aftermarket catalytic converters are inferior to OEM ones, as some aftermarket products can perform just as well. However, most car owners lack in-depth knowledge about automotive parts, making it difficult for them to determine whether the catalytic converter they purchase meets the required standards. If a car owner is not familiar with vehicle structures, it is advisable to replace the catalytic converter with an OEM part at a 4S dealership. The quality of the catalytic converter directly affects whether the vehicle can pass annual inspections. If a catalytic converter is found to be damaged, it should be promptly repaired or replaced at a service center.

However, the automotive parts market is a mixed bag, and without professional knowledge, it is best to opt for an OEM catalytic converter from a 4S dealership. Generally, OEM catalytic converters offer better compatibility than aftermarket ones, effectively catalyzing harmful substances in exhaust emissions. Using a substandard catalytic converter can not only lead to excessive emissions but also increase exhaust backpressure, negatively impacting the engine's power output.
