Your vehicle's exhaust system is more than just a tailpipe and a muffler. In fact, it is one of the most complex systems on your vehicle.
The manifold is attached to the vehicle engine. It collects exhaust from the cylinders and directs it into the exhaust pipe. Gaskets seal the connection of the manifold to the engine and to other joints. A cracked or loose manifold or a leaking or damaged gasket can allow dangerous gases to enter the passenger compartment of a vehicle. One of these gases is carbon monoxide, which is colorless, odorless and deadly. For this reason, it is important drivers keep their exhaust system in good repair.
The pipes that connect the various parts of the exhaust system can rust or be damaged by rocks or other road debris. Such damage can cause dangerous gases to leak into the air.
The catalytic converter is the next component of your vehicle exhaust system. It sort of looks like a muffler. Its job is to change dangerous gases into harmless carbon dioxide and water. The catalytic converter doesn't require any regular maintenance, but it can wear out. If it fails, in some areas, you will need a new catalytic converter to pass an emissions test in Wisconsin.
Oxygen sensors in the exhaust pipe monitor the oxygen content of the exhaust. This helps the vehicle engine's computer keep the fuel-to-air mixture at optimal levels.
The muffler is also part of your vehicle exhaust system, but it deals with a different kind of emission. It keeps your vehicle from emitting bad sounds. Mufflers act like finely tuned musical instruments. They create a feedback of sound waves to absorb or decrease the noises made by your engine. Different mufflers can create different sound waves, so you can actually “tune” your car to produce a particular sound, anything from whisper to rumble.
The entire exhaust system is attached to your vehicle by hangers and clamps. These fasteners can rust, come loose or break. The components of the exhaust system can get very hot, so when the hangers or clamps fail, these hot components can come into contact with other parts such as wires and hoses. These can melt, causing serious and damage to your vehicle. Good car care requires that you have your exhaust system inspected regularly.
