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 goblackops.com.au, 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.
