Cars of today may have the problem of back pressure if it fails to get rid of excess gases. Most vehicles that are straight from the factory don’t always have free flow exhaust system instead, it is only using small diameter piping than what the car needs exactly. If you take a look at the exhaust manifold, you’ll notice that the bends aren’t bent in mandrel manner, creating better airflow.
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. Best branches in the market are using mandrel bends and some even are coated in ceramics for improved heat reduction. Not only that, it is flow tested to make sure that it is flowing the air out efficiently.
Head pipe – the main function of a head pipe is connecting the branches to catalyctic converter and then to mufflers. It is pretty normal to see it not having much bends and follow a straight path.
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. A catalyctic converter is most instances coated using palladium and platinum and has beads/honeycomb. This in return causes chemical reaction that is converting the bad gases to good ones.
Muffler – deadening the loud sound produced by a car is the function of mufflers. The muffler does this by forcing the sound waves to bounce against each; this process cancels the noise. Actually, many cars have second mufflers or sometimes two parallel mufflers. The final muffler in most cases has a couple of exhaust tailpipes connected to it. This is mostly done for aesthetics purposes only especially when you see the tips to be chromed.
Tailpipe – it’s the last part of an exhaust system and it consist of piping from muffler all the way back. Whether you believe it or not, majority of the aftermarket tailpipes you can purchase today have a beautifully chromed tip that’s either single or double 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.
