Is Aftermarket Catalytic Converter Loud: How To Reduce Noise Level

‍An aftermarket component called a catalytic converter is mounted over the exhaust manifold. It is essential for decreasing dangerous exhaust gas emissions. A cat-con also lessens a car’s emissions of CO, HC, and NOx. It achieves this at the expense of performance and noise, though. Installing a catalytic converter is mostly done to use it as an emissions control device or to lessen pollutants that are released from the exhaust system. While some individuals feel that it slows down and increases noise in their car, this is unimportant. Read on to find out more about these components and how to lower their noise level if they are too loud for you to tolerate if you are concerned about whether or not your automobile has an aftermarket catalytic converter.

What Is The Cause of Noise From Aftermarket Catalytic Converters?

The car’s exhaust manifold has an aftermarket cat-con installed on it, and whenever exhaust gas passes through it, it is transformed into harmless byproducts like CO and CO2. The dangerous gases are completely broken down when the catalytic converter is brand-new. But over time, it starts to lose effectiveness and produce fewer results. Emissions of CO, HC, and NOx start to rise. The car engine starts to become louder when the catalytic converter is unable to completely degrade the hazardous gases. When a catalytic converter breaks down dangerous gases, heat is produced. The heat increases the amount of noise the car makes. The catalytic converter becomes ineffective and unable to do its job above a certain temperature.

How to Reduce Noise Level of Aftermarket Catalytic Converter?

There are a few things you can do to lower an aftermarket catalytic converter’s noise level. First, check to see that the engine is in good shape and is using high-quality fuel. It can become noisier if the engine is in poor shape or if low-quality fuel is used. Additionally, you might try adjusting the engine timing. You can attempt to change the timing if your car has a variable-timing engine. The timing of the exhaust can likewise be altered in a similar manner. Altering the flow of the exhaust gases into the catalytic converter is another option. Installing a new brand of aftermarket cat-con will accomplish this.

Why Is Aftermarket Catalytic Converter So Loud?

The fact that an aftermarket cat-con is producing additional heat indicates that the gases are not being completely broken down. When the catalytic converter is malfunctioning, the exhaust system becomes louder as well. The exhaust gas is supposed to break down into CO, CO2, and H2O when it goes through the catalytic converter. However, the catalytic converter cannot completely degrade the gases if there is a blockage inside of it. The exhaust system continues to be noisier than normal. The sound gets louder the longer CO2 is left in the exhaust system. Furthermore, the fuel efficiency of your car decreases when the CO2 level rises.

Tips To Reduce Noise Level of Aftermarket Catalytic Converter

There are a few techniques for lowering an aftermarket catalytic converter’s noise level. To start, you can make sure that you replace the fuel filter and engine oil according to the suggested schedules. Less wear and tear and hence less noise would come from a clean engine. Attempting to clean the exhaust system’s interior is another option. Installing a high-flow catalytic converter and exhaust system is another way to attempt and lessen the pressure drop within the exhaust system.
