Diesel Exhaust System: Things You Need To Know Before Buying

It may seem simple to buy your car. However, it isn’t. For some people, it may seem easier. To make sure you can properly understand not only how to drive but every part of the car.

The exhaust system, which is responsible to exhaust the gases from a car, is an essential component. This gas escape route can include many pipes, including other pieces such as the catalytic converter and tailpipe. The overall design of the system may make it more complicated.

Dodge Ram is a car model to have a 3rd Gen Cummins exhaust design and here are some parts of it that will be helpful for you in learning:

Exhaust Manifold

The exhaust manifold connects directly with the engine. It is usually made of steel or aluminum and stainless steel. This part collects exhaust from each cylinder and combines it to form one pipe. The size of a vehicle will determine whether it has one or multiple exhaust manifolds. They are composed of smooth, curving passages that increase exhaust flow.

Oxygen Sensor

The oxygen sensor measures how much oxygen is in the exhaust. This information is used by the computer to adjust fuel consumption and improve fuel economy. Two oxygen sensors can be found on most vehicles.

Catalytic Conversion

The catalytic conversion works by converting harmful gases to water vapor and carbon dioxide. This component reduces vehicle emissions and helps to ensure that your car’s impact on the environment is minimal.


The muffler helps reduce noise and soundproof the engines of your vehicle. This component dampens vibrations from engine sound pressure through acoustic quieting. There are two types. Baffle chambers can be used to reduce noise and the second to lower backpressure.

Exhaust Pipe

The exhaust tube connects all components of your exhaust system. These pipes allow exhaust gas to move as efficiently towards the vehicle’s rear as possible.

A car with a Dodge Cummins diesel engine might be a good choice if you’re looking for one that is both efficient and cost-effective.
