How Does The Porsche Exhaust System Work?

Keeping Porsche exhaust system in good shape is not only important for fuel mileage, but also for your safety and the environment. One should know the functioning of exhaust systems, and in what cases they fail. Since exhaust systems blow out harmful gases, it is imperative to carry out frequent checks. Let us analyze some of the important parts of a Porsche exhaust system and how they function.

Exhaust Manifold

The exhaust manifold is attached to the head of the cylinder, and it takes each cylinder’s exhaust, combining it into single pipe. The manifold can be made of cast iron, stainless steel, aluminum or steel.

Oxygen Sensor

The amount of oxygen present in the exhaust is determined by an oxygen sensor, which is present in most modern fuel injected cars, including Porsche. Using this, the system adds or subtracts the fuel content needed to maintain the right mixture for higher fuel efficiency. The oxygen sensor is mounted in the exhaust pipe or in the exhaust manifold.

Catalytic Converter

This shawl like part is responsible for converting harmful hydrocarbons and carbon monoxide to carbon dioxide and water vapor. A few converters also cut down nitrogen oxides. It is generally mounted between the muffler and the exhaust manifold.


The Muffler does the job of alleviating the noise levels produced by an exhaust. Since combustion is nothing, but a series of explosion, it can be really noisy. The mufflers used in Porsche utilize baffles to dissipate the energy and reduce the noise. A few mufflers make use of fiberglass packing, which is good for noise absorption.

Exhaust Pipe

Exhaust Pipe plays an important role in carrying the gas out your tail pipe. It can be made of aluminized steel tubing, stainless steel or simply steel. Out of the three, the stainless steel is highly corrosion resistant.

What Are The Common Issues With Porsche Exhaust System?

Corrosion is certainly the worst enemy for your exhaust system. Rusting is a process of iron oxide formation, when moisture reacts with iron in the steel. Water vapor or moisture is a by-product of combustion, while it can also come from outside. Short trips can reduce the life span of your system, since the water may not a get a chance to evaporate.

If you are good with driving only short distances, make sure to have a stainless steel exhaust, if you don’t have one already. In case you live in an area where salt is used on the roads during the winters, make sure you are washing the bottom of your car, every few weeks. Most people don’t know but salt can act as a catalyst for corrosion. After washing your car, you should always run the engine to wipe off all the water that may have settled on the pipes.
