When you are looking at cars to buy, you often focus on the look of the car, the price, the convenience and of course the fuel consumption. But there are many more features that you can consider, especially if you are an automotive enthusiast. This includes things like top speed, torque, horsepower, the amount of cylinders, transmission, and type of engine. But don’t forget the exhaust system; it’s an important part of any vehicle and can have an influence on the performance that you get from the vehicle. If you are looking at a Pontiac exhaust system, you’ll notice just how important this system can actually be.

Whether you own a Pontiac G5, Torrent, or Solstice, all these vehicles have one thing in common; they all have an exhaust system. Actually, every car has an exhaust system and one can hear when an exhaust system might need maintenance but have you ever wondered why each vehicle has one. The car’s exhaust system is responsible for carrying away gasses that are burned in the combustion chamber that are dangerous and harmful to the environment and humans. That’s why a Pontiac exhaust system is so important.

The Pontiac exhaust system consists of an exhaust manifold, an oxygen sensor, a Pontiac Catalytic Converter, a muffler and exhaust pipes. The exhaust manifold is attached to the cylinder head and combines each cylinder’s exhaust into one pipe. This part can either be made from steel, stainless steel, aluminum or sometimes cast iron. The oxygen sensor is present in modern cars and is used to monitor how much oxygen is present in the exhaust system. With this figure, the computer can add or subtract the amount of fuel needed to obtain the perfect mixture to get the best fuel efficiency.

The Pontiac Catalytic Converter converts harmful carbon monoxide and hydrocarbons to carbon dioxide and water vapor. Some converters can reduce harmful nitrogen oxides. The converter can be found between the muffler and exhaust manifold. The muffler is the part that quiets down the exhaust to an acceptable sound level. Some mufflers use fiberglass packaging that helps with the sound absorption as gases flow through. The exhaust pipe carries the gas through this journey and then out the tail pipe. The exhaust tubes are usually made from steel or stainless steel. Another material used is aluminum that has a better corrosion resistance.

Unfortunately, corrosion is the exhaust system’s worst enemy and is caused by the presence of moisture or water vapor in the exhaust. This may result in a catalytic converter replacement. When a car only travels for a short trip, the water does not have the chance to evaporate and rusts if the pipes are made of steel. So you may need to replace your Pontiac Catalytic Converter, or even replace additional Pontiac exhaust parts.
