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. 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. To create better airflow of the exhaust manifold, the bends don’t follow a mandrel manner bent.

As for naturally aspirated vehicles available today, it is best that you work first on its induction and exhaust prior to anything else. As you read the next lines, you will be able to know other parts of exhaust systems and its uses.

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 you can find in the market uses mandrel bends and some are coated in ceramics for an 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 normally has straight path without much bending.

Catalyctic converter – this converts the dangerous chemicals like carbon monoxide, hydrocarbons as well as nitrogen into oxygen, nitrogen, water vapor and CO2. Digging deeper to what a catalyctic converter is, you’ll see that it compose of beads/honeycomb coated in palladium and platinum. In return, this is making chemical reaction that converts the bad gases to good ones.

Muffler – mufflers have one and one function only, and it’s to lower the loud sound made by the vehicle. It is able to do this by getting sound waves to bounce against each and therefore, cancelling them. Actually, many cars have second mufflers or sometimes two parallel mufflers. There are often a couple of exhaust tailpipes that are connected to the final muffler. This is mostly done for aesthetics purposes only especially when you see the tips to be chromed.

Tailpipe – this basically consist of a piping from the muffler to 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. Most bends are located here as the piping has to curve up and over the vehicle’s rear axle. In fact, there are suppliers that even put lights onto the tips of their exhaust.
