Everything You Need to Know About Your Exhaust System

Today, we will go through the complexities of your vehicle's exhaust system and answer these common questions: What is the exhaust system? What are the parts? And what do they do? 


The engine usually ejects the various gases from the combustion chamber that need to go somewhere. This is where the exhaust system comes in. The entire system is responsible for moving gases around and converting these harmful chemicals into breathable gases before releasing them out of your car. The overall system comprises multiple pipes that work together to reduce the output of harmful emissions. The parts involved in the intricate process include the exhaust manifold, catalytic converter, oxygen sensor, tailpipe, muffler, and resonator. 


The exhaust manifold is at the beginning of the process. It collects the fumes from the cylinders within the engine's combustion chamber and moves them through the exhaust pipe.


The catalytic pipe converter then transforms the toxic fumes, such as carbon monoxide, into water vapor and carbon dioxide (which are safer to breathe in). 


The oxygen (O2) sensors then detect the level of O2 in the exhaust stream. This info is used by the powertrain control module for fuel control and to control converter productivity.


The tailpipe directs the water vapor and CO2 out of the vehicle.


The muffler is "muffles" or dampens the loud sounds that come from the engine. This part of your car has different chambers of tubes with openings that produce waves to remove sound frequencies. 


The resonator is similar to the muffler, where it limits the vibrations that come from the engine. It also improves airflow.
