Toyota 17410-61021 Front Exhaust Pipe Assembly

Due to a federally mandated extended warranty covering emissions-related components like the catalytic converter, it is advisable to consult a dealer service department before incurring replacement costs. Some early carbureted models feature an oxidation catalyst system, which operates similarly to later three-way catalytic converters; if the converter overheats beyond 1,445 degrees F (785 degrees C), a thermo sensor will deactivate the Air Injection system, necessitating inspection by an exhaust system repair facility. To minimize hydrocarbon, carbon monoxide, and oxides of nitrogen emissions, vehicles are equipped with a three-way catalyst system that converts these harmful substances into harmless nitrogen, carbon dioxide, and water, with the catalytic converter positioned in the exhaust system akin to a muffler. Regular checks should include inspecting the catalytic converter-to-exhaust pipe mating flanges and bolts for tightness and leaks, examining the catalytic converter protector for dents or damage that could contact the converter, and ensuring the heat insulator is intact with sufficient clearance from the catalytic converter.
