Where is the catalytic converter located on a Corolla?

[MacRuth]

The catalytic converter on a Corolla is installed in the vehicle's exhaust system. Below are specific details about the clogging levels of the catalytic converter: 1. Mild clogging stage: At this stage, chemical complexes adhere to the surface of the catalyst, manifesting only as a reduction in the exhaust purification function and exceeding emission standards. Colored smoke from the exhaust pipe is often visible. 2. Moderate clogging stage: Chemical complexes have accumulated to a certain extent on the catalyst surface. This stage is characterized by increased exhaust backpressure, higher fuel consumption, and reduced power. The engine warning light typically illuminates at this point. 3. Severe clogging stage: Due to significant clogging, the working temperature of the catalytic converter rises. This stage presents as a severe loss of power, frequent stalling, and in extreme cases, the exhaust pipe may glow red, produce abnormal noises, and emit foul odors.
