Will the noise increase if the car's three-way catalytic converter is removed?
1 Answers
Removing the car's three-way catalytic converter will increase the noise because it leaves a large exhaust space, allowing exhaust gases to rapidly discharge into the atmosphere, which naturally amplifies the engine noise. Below is relevant information about the car's three-way catalytic converter: Appearance: The three-way catalytic converter looks like a metal can, but inside it contains a 'substrate' for purifying exhaust gases. This honeycomb-shaped ceramic substrate is coated with a precious metal slurry, primarily composed of platinum, rhodium, and palladium. Function: The precious metals act as purifying agents, reducing HC and CO in the exhaust gases into water and CO2, while decomposing NOx into nitrogen and oxygen. This is the exhaust purification function of the three-way catalytic converter.
