Components Of The Exhaust System

The exhaust system begins at the engine and ends at the tailpipe at the rear of your vehicle. It is composed of a series of pipes and chambers. While most vehicles only need one exhaust system from, vehicles with engines that have eight cylinders have two exhaust systems, one on each side. In the event that you have a vehicle with two exhaust systems, it is extremely important that both systems are running efficiently.

There are five main parts to a normal exhaust system. The first part is the exhaust manifold. This component is attached to the engine. The exhaust manifold funnels the exhaust gasses from multiple cylinders into one single pipe. This part of the exhaust system will also burn any remaining fuel that was not burned in the engine.

The next part of your vehicle’s exhaust system is the oxygen sensor. This part is located either near or in the exhaust manifold. The sensor reads oxygen levels and sends the data to the car’s computer. Your vehicle’s computer will then calculate how much fuel is needed by the engine to get the best fuel efficiency possible.

Another important piece of the exhaust system is the catalytic converter. After the exhaust manifold, the catalytic converter will convert carbon monoxide and hydrocarbon gasses which are extremely harmful into carbon dioxide and water vapor. This not only ensures the safety of the occupants of the vehicle but also makes the exhaust gasses safer for the environment. It is possible to still operate your vehicle without this component; however, it is illegal to do so in most states.

The exhaust pipes are a vital component of the exhaust system. These pipes carry the exhaust gasses through the entire system starting with the exhaust manifold and ending with the tailpipe where the emissions exit the vehicle.

The muffler is typically connected to the tailpipe of your vehicle. It is a metal box that contains a series of tubes that helps quiet the combustion sounds that occur throughout the exhaust system. The back of the muffler has a resonator that uses built-up pressure to cancel out sound waves. Some mufflers use fiberglass to absorb the sound waves instead.


The Importance of a Car Exhaust System

Many people tend to ignore the exhaust system of a car. You may think that the exhaust system does nothing but remove waste products from the combustion process. While the exhaust system does just that, the way in which these waste products are removed from the machine is critical to the operation of the machine. 

The exhaust system has three main functions: First, it removes combustion residue from the engine so that it can continue to run unhindered, thus ensuring the engine runs smoothly. An efficient exhaust system allows exhaust gases and connections to exit the system quickly. For more information about how the exhaust systems function can work, you can check it via

Another function of the exhaust system is to reduce the noise generated by the engine. Noise is one of the "wastes" generated by the engine. The exhaust gases leave the engine at very high pressure. If these gases came directly from the engine, the noise would be enormous. 

The third function of the exhaust system is to eliminate polluting emissions. When an engine burns fuel, it creates gases that pollute the air, such as hydrocarbons, carbon monoxide, and nitrogen oxides. The exhaust system cleans exhaust gases through the catalytic converter and decomposes harmful gas compounds. 

Mazda catalytic converters can be found at wholesalers. However, there is an easier way to buy parts for Mazda. The most convenient and fastest way to buy parts for Mazda is to visit a reliable online auto parts supplier who has a strong reputation as a great source for premium and affordable auto parts and accessory prices.
