Almost every car owner knows something about his/her car exhaust. But really what does a exhaust do in a car. Well the exhaust does a lot work than engine noise control, exhaust also removes the harmful gases produced in your engine through the exhaust tail pipe.
The exhaust system comprise of five major parts, the exhaust manifold, oxygen sensor, catalytic converter, muffler and the exhaust Pipe. These five components of the exhaust system works together to archive the three major functions of the exhaust system.
The four major functions of the exhaust are control noise, carry away gases, improve engine performance and improve fuel consumption. An exhaust system is used to guide reaction exhaust gases away from a controlled combustion inside an engine. The entire system conveys burnt gases from the engine and includes one or more exhaust pipes.
What Is A Muffler and What Does a Muffler Do?
The muffler is a compartment that is located right at the tail end of the exhaust tailpipe. The compartment is situated inside the exhaust system of the car.
Now, there might be a tailpipe extension down there, perhaps a couple of mechanical clamps supporting the additional pipe section, but this noise attenuator is still located at the rear end of the piping. It’s generally filled with chambers and perforated tubes.
Ideally, the Muffler has being designed to absorb engine sound and makes it possible for the car to run without producing lots of noise. Although, some modifications can be done to make the engine produce a throaty roar, this could be done too by some after market Muffler.
Importance of car exhaust and Muffler
It is not a new thing any more to car owners that the exhaust system is very important component if the car that makes the more comfortable. The importance of the exhaust system goes far from just noise control and exhaust gas filtration.
The exhaust system houses the oxygen sensor which sense oxygen intake and regulates amount of fuel needed to burn the oxygen. If the car exhaust is leaking, the system will take in more oxygen than required.

To burn this excess oxygen, the combustion chamber will require more fuel which will then lead to increased fuel consumption. However, control noise, carry away gases, improve engine performance and improve fuel consumption are the major functions of the exhaust. The importance of the exhaust system have been elaborated as seen below.
- Active engine control Noise
After the harmful elements have been removed from the exhaust gases, they travel through your vehicle’s muffler which dampens the sound of the gases leaving the vehicle.
- Exiting away harmful Gases
Exhaust gases are collected by the exhaust manifold and eventually routed out of the vehicle. The exhaust manifold acts as a funnel, catching gases from all cylinders and releasing them through a single pipe.
- Improved Engine Performance
The exhaust is design to take certain amount of oxygen and release certain amount of gases at a time. So the longer it takes the system to take in oxygen and release gases will determine how power is generated at a time.
If you want more power to be generated then you can go for and aftermarket exhaust of exhaust system modification. When the exhaust is modified to take in more oxygen then expect more fuel to be consumed but this time with faster and better speed performance.
- Fuel Management
The exhaust controls fuel management by taking in the right amount of oxygen needed and burning it in the combustion chamber. The Oxygen sensors in the exhaust system is in charge of fuel management.
When there is a leak in the exhaust system then there would be more oxygen intake by the exhaust. If the oxygen sensor senses more oxygen intake in the system then it require more fuel or gasoline to burn the excess oxygen.
