Will the sound become louder after removing the catalytic converter?

[HarperMarie]

Removing the catalytic converter will make the sound louder. Here are the relevant details: 1. Function of the catalytic converter: It filters some incompletely burned gases. If the catalytic converter is not installed, your vehicle may fail the emissions test during the annual inspection after six years. 2. Catalytic converter: It refers to the process of converting harmful gases such as CO, HC, and NOx emitted from the vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. The main component is the catalytic converter, whose carrier is a porous ceramic material installed in a specially designed exhaust pipe. It is called a carrier because it does not participate in the catalytic reaction itself but is coated with precious metals such as platinum, rhodium, palladium, and rare earth coatings. It is the most important external purification device installed in the vehicle's exhaust system.
