All About Exhaust System
It is imperative for a car of any type to get rid of its waste or excess gases because restrictions of such will lead to back pressure. Whether you believe it or not, most cars that are straight from the factory do not have free flow exhaust system instead, it uses small diameter piping which is bigger than what the car needs. To create better airflow of the exhaust manifold, the bends don’t follow a mandrel manner bent.
Say for example that you got a naturally aspirated vehicle, it is necessary that before you work on any modifications, you should work first on the induction and exhaust. You will learn about the various parts of exhaust system in the next lines.
Manifold/exhaust headers/branches – this is taking the gases from the cylinder of the car’s engine which combines it to 1 pipe that is interconnected to the head pipe which is found underneath the car. The best branches that are available in the market make use of mandrel bends while others are ceramics coated for better heat reduction. In addition to that, they are flow tested to ensure that it flows the air out in the best way.
Head pipe – the main function of a head pipe is connecting the branches to catalyctic converter and then to mufflers. It is normally has straight path without much bending.
Catalyctic converter – it is converting dangerous chemicals similar to carbon monoxide, hydrocarbons as well as nitrogen to CO2 or carbon dioxide, water vapor, nitrogen and oxygen. As we discuss its function in greater detail, you will see that this has beads/honeycomb that is coated in palladium as well as platinum. With this in the exhaust of the car, it is able to transfer the bad gases into good one.
Muffler – the job of the muffler is deadening the loud sound created by the vehicle. Getting the sound waves to bounce back and forth to it is how it is able to do it. A lot of cars actually have a second muffler or at times, even two parallel mufflers. The final muffler in most cases has a couple of exhaust tailpipes connected to it. Usually, this is done for aesthetics only particularly when its tips are chromed.
Tailpipe – this is the last part of the exhaust system and has piping from the vehicle’s muffler and all way back. Aftermarket tailpipes that you’ll find in automotive shops have a very attractive chromed tip. Due to the reason that the piping should curve up and over the axle on the rear, you’ll typically find most bends on this location. In fact, there are suppliers that even put lights onto the tips of their exhaust.
