What Happens If the Catalytic Converter Is Hollowed Out?

[StevenDella]

After the catalytic converter is hollowed out, the vehicle's exhaust noise will become significantly louder, and the exhaust odor will become more pronounced. The vehicle is highly likely to fail its annual inspection due to excessive exhaust pollution. The catalytic converter is primarily composed of asbestos fiber felt, purifiers, substrates, and metals such as platinum, rhodium, and palladium. Among these, platinum, rhodium, and palladium are the main catalysts in the catalytic converter, effectively reducing the amount of nitrogen oxides and particulate matter in the exhaust. The following is an introduction to the catalytic converter: The catalytic converter is the most important external purification device installed in a vehicle's exhaust system. It converts harmful gases such as CO, HC, and NOx emitted from the vehicle's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions.
