Before selecting after market exhaust parts, its important to become familiar with the basics. We won’t into great detail, so put away the note pad and we promise to have you out of class before the lunch bell rings.

Now, just like anatomy of humans, the anatomy of a vehicle’s exhaust will vary from vehicle to vehicle. However, all exhausts work in the similar way in order to remove harmful exhaust gases from the engine which are produced while the engine is running.

The Journey Starts with an Exhaust Manifold – 

For time’s sake, we will skip the engine anatomy and head straight to the beginning of the vehicle’s exhaust. Because the engine uses combustion to operate, we have left over gasses that must escape. These emissions from the engine cylinder heads are collected into one pipe – the exhaust manifold. It is a part that connects all the engine cylinders to the exhaust system. The exhaust manifold is usually made from stainless steel or cast iron.

Next Stop, the Catalytic Converter –

Next, the emissions leave the manifold and head to the catalytic converter. It is a small metal chamber that receives exhaust gasses and changes the chemical nature of them (by coming in contact with metals such as platinum) to reduce the volume of bad emissions from the exhaust manifold. Catalytic converters became mandatory in the 1970’s to comply with the U.S. Environmental Protection Agency’s stricter regulation of exhaust emissions.

The Muffler –

Finally, the exhaust pipe carries the cleaner emissions into the muffler, which reduces the associated noises as the exhaust exits into the air. Mufflers are designed to minimize the sound from the engine by directing the the sound waves from engine, to the resonator chamber, then through the perforations tubes (or baffled chambers) within the muffler. That will cancel or “muffle” the sounds.  It is important to note that the faster your engine can get rid of exhaust gases, the faster it can take in fresh oxygen and generate more power. Therefore, efficient exhaust flow is essential to power output.

There you have it – from the beginning, all the way to the tail pipe. A basic and simple explanation on how your exhaust system works.  Stay tuned next week for our next post as we discuss the benefits and importance of after market exhaust performance parts.
