Exhaust System

An exhaust system is usually piping used to guide reaction exhaust gases away from a controlled combustion inside an engine or stove. The entire system conveys burnt gases from the engine and includes one or more exhaust pipes. Depending on the overall system design, the exhaust gas may flow through one or more of:


  • Cylinder head and exhaust manifold
  • A turbocharger to increase engine power.
  • A catalytic converter to reduce air pollution.
  • A muffler (North America) / silencer (UK/India), to reduce noise.

We understand that vehicles can be a complicated topic to try and understand. We also understand the exhaust system of a vehicle is such a topic. Which is why we are going to demystify car exhaust systems for you [Our Clients]


Hopefully by the end of this you will have a firm understanding of how an exhaust system works and the parts that make them up.

Exhaust Manifold:

The exhaust manifold on a vehicle is the upper portion of the exhaust system that is attached directly to the engine on it’s side. It is the first portion of the exhaust system that receives the used exhaust that is emitted from the vehicles engine. The manifold itself becomes extremely hot to burn any excess fuel that was left behind. It then funnels down into the main portion of the exhaust system


Exhaust Pipe

The exhaust pipe comprises the bulk of the overall exhaust system. The exhaust pipe can be made from various metals, but usually, it is made from either metal or aluminum. Its main function is to move the exhaust gases from inside the engine towards the tail pipe of the vehicle where it can be emitted.

Muffler/Catalytic Converter:

Once the exhaust gas travels through the exhaust pipe, it enters the muffler. The muffler is made of metal as well and its main responsibility is to reduce the noise made by the sounds of traveling exhaust gases as well as the catalytic converter, thus, it muffles the noise. The catalytic converters sole job is burn up any excess fuel that has made it there. In this way, it is not emitted out of the tail pipe unburned and left to the environment.


Tail Pipe:

The final stage of the emission flowing process is once the gases actually enter the tail pipe. The tailpipes sole and simple purpose is to allow the car exhaust to enter the outside air. The tail pipe is the part of the exhaust system that is noticeable when behind a car. There are also countless devices that can be added at this point to “trick” your car out. You can add whistlers to create a loud screeching sound, have flames shoot out, and any number of other things.
