Catalytic Converter Replacement: A Complete Guide for Your Exhaust System A catalytic converter is a crucial part of a vehicle's exhaust system, responsible for reducing harmful emissions by converting toxic gases into less harmful substances. If your vehicle shows signs like poor engine performance, a check engine light, strange noises, or a foul smell from the exhaust, it may be time to replace the catalytic converter. The exhaust catalytic converter is situated between the engine and muffler, ensuring compliance with emission standards. Regular maintenance, such as using the right fuel and avoiding short trips, can extend the life of the converter. Replacing it involves diagnostic testing, lifting the vehicle, removing the old unit, and installing a new one.
