[MacRyder]

Solution for loud noise after hollowing out the catalytic converter: Replace with a new catalytic converter. Below is relevant information about the catalytic converter: 1. Composition: The catalytic converter mainly consists of asbestos fiber felt, purifying agent, carrier, and metals such as platinum, rhodium, and palladium. Among these, platinum, rhodium, and palladium are the primary catalysts in the catalytic converter, effectively reducing nitrogen oxides and particulate matter in the exhaust. 2. Function: The catalytic converter is installed as the most important external purification device in the automobile 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.
