All About Exhaust System

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. 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. In the next paragraphs, you’re going to discover the different parts of an exhaust system.

Manifold/exhaust headers/branches – these are taking the gases from different cylinders and combining them into 1 pipe that is interconnected to another one underneath the car or called the head pipe. The best branches that are available in the market make use of mandrel bends while others are ceramics coated for better heat reduction. There are several flow test performed on it as well to guarantee that the air is exerted in the best manner possible.

Head pipe – connecting branches to catalyctic converter and to the muffler is the main function of head pipe. It is pretty normal to see it not having much bends and follow a straight path.

Catalyctic converter – converting carbon monoxide, hydrocarbons as well as nitrogen, which are all dangerous chemicals to carbon dioxide, nitrogen, oxygen and water vapor is the purpose of catalyctic converter. A catalyctic converter is most instances coated using palladium and platinum and has beads/honeycomb. 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. A lot of cars actually have a second muffler or at times, even two parallel mufflers. There are often a couple of exhaust tailpipes that are connected to the final muffler. Usually, this is done for aesthetics only particularly when its tips are chromed.

Tailpipe – it’s the last part of an exhaust system and it consist of piping from muffler all the 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.
