A Comprehensive Guide on Aftermarket Exhausts Systems


Remember the first time; you heard the word anatomy in the classroom of your school? Yes, this discussion might have overwhelmed you at the start but you might have overlooked it as just another part of the syllabus. But for the adventurous hot car drivers knowing the real meaning of the “anatomy of the exhaust” is a must. This article provides a distinct insight about this enigmatic exhaust anatomy that overwhelms car fanatics quite often.

Why Will You Choose Aftermarket Exhaust Components?

The exhaust systems that are manufactured by the company are designed to muffle the sound of the vehicle. This means that it restrict the flow of the outgoing exhaust gases out of the engine, creating something known as backpressure. Most of the engines need some of the backpressures to work properly. It is important for the engine to use some power that it generates to cram the exhaust gases from the tailpipe instead to use the power to drive out the car. If you like to steal the power back, you can surely replace the factory OEM parts with the aftermarket exhaust systems for improving the performance of the exhaust systems.  Here are some of the exhaust parts that require replacement with the aftermarket ones.

  • Headers/ Exhaust Manifolds:

The first exhaust parts that handle the ejected exhaust gases from the engine are the headers. It is also called the exhaust manifolds in the stocked form. The headers are attached to the cylinder heads and exhaust the gases from the combustion chambers. The headers that are brought from the market are mainly mandrel-bent to eliminate the exhaust restriction that allows the gases to come out freely from the engine. This help in reducing the power-robbing backpressure and help in building up the exhaust flow velocity to generate the energy pulses that generally pulls the gases from the engine. The headers that are of full-length and short in dimensions. They are also available in multiple configurations that include tri-Y and 4-into-1.

  • Downpipe:

They are also known as the head pipes. These pipes generally link the headers with the mufflers. In between the two points, the downpipe is mainly interrupted by the use of the catalytic converter that depends on the applications.

  • Catalytic Converter:

If your car was manufactured after the year 1975, there are several chances that they are original factory equipments. As like the muffler that mainly works to lower down the exhaust noise, the catalytic converter is mainly installed to reduce the harmful emissions your car release in the atmosphere.

  • Muffler:

It is one of the main parts of the exhaust systems. The muffler is mainly used to reduce the noise of the exhaust gases coming out from the vehicle. May be the function of the muffler seems to be very simple, but the functions of the mufflers varies from vehicle to vehicle.

Apart from these components, the exhaust system kits have the crossover pipes and the tailpipes. Considering the above mentioned points it can be easily concluded that the aftermarket exhaust systems are more useful than the OEM parts.
