Engine Exhaust Pipes
The exhaust system is responsible for expelling exhaust gases from the combustion chambers. Before being release at the exhaust, the gases go through the catalytic converter and muffler. The muffler reduces noise in the exhaust.

The exhaust system comprises of pipes that are designed with different shapes. They are connected to each other and are located underneath the car. They are shaped to accommodate different parts of the exhaust system. For instance, they are bent to accommodate other components such as the axles. While most segments inside the exhaust pipes are specialized, the exhaust pipe is generally designed to move exhaust gases towards the car rear.
An example of specially designed pipe is a Y shaped pipe. It has two openings which correspond to two opening of the exhaust manifold. It combines the engine waste gases. Similar the Y pipe can create a double exhaust system where two tailpipes release exhaust gases each at either side of the vehicle. The final part of the exhaust part can either be straight or angled. It is the only visible part of the vehicle exhaust system.
Other important pipes in the exhaust system are the intermediate and balance pipes. Intermediate pipes are attached to either the resonator or muffler. The balance pipes are usually incorporated in dual exhaust systems. Basically, they equalize the pulses of exhaust flowing on the passenger and driver sides of the vehicle. Air pipes are yet other valuable pipes in the exhaust system. Their function is to insulate and shield heat by providing an additional layer for gases to flow in.
The tail pipe is probably the most known among the exhaust pipes. It protrudes from underneath the vehicle bumper and has a large opening. High end vehicles have performance exhausts which consist of substantial metal.
All this segments have their functions as outlined above. Connecting different pipes is more efficient than having to shape a single heavy pipe to fit the structure of the vehicle.
Due to their location the tailpipes are prone to damage as it exposed to moisture and debris. Since most tail pipes are metallic, exposure to moisture causes corrosion. When the tail pipes are corroded they become inefficient in removing exhaust gases. Some Exhaust pipes are made of stainless steel or aluminized steel to prevent corrosion.
Iron exhaust pipes are the most susceptible to corrosion or rust. Moisture from the combustion process also poses a risk of corrosion. Additionally, exhaust pipes wear out depending on driving conditions, materials and other factors. If your tailpipe has corrosion or is damaged you should seek a replacement immediately.
