Toyota 17410-21540 Front Exhaust Pipe Assembly

First of all, the catalytic converter is a device that reduces harmful exhaust emissions by converting poisonous gases into less harmful ones. It is made of a ceramic honeycomb structure coated with precious metals, which act as catalysts. The converter gets hot during the reaction and can be damaged by rough treatment or driving through deep water. To ensure its proper functioning and longevity, it is important to use unleaded petrol, maintain the ignition and fuel systems, avoid engine misfires, and not push or tow-start the car. Also, do not switch off the ignition at high engine speeds, use fuel or oil additives, continue using the car if it burns excessive oil, park in areas with high vegetation, or strike the converter during servicing. A blocked converter may cause a substantial loss of power.
