Exhaust systems

The exhaust system is a series of piping that is used to guide exhaust gases from the engine away from the engine. The system moves burnt gases from the engine through either one or more exhaust pipes. The first part of the exhaust system is the header manifold. It is designed to collect the gasses that come from the cylinders into one set of pipping. The factory made ones are made out of cast iron, but aftermarket ones that you can purchase and install are sometimes made out of other materials. The manifold is purely a performance piece. Getting an aftermarket manifold and increase the performance of your car. It does this by allowing easier flow for the exhaust allowing more to be pushed out. Next would be a catalytic converter, but some systems take this out which is illegal in some places. Lastly we have the tailpipe. This is the part that most people think of when they hear exhaust, because this is the only part you can easily see. This is where the gasses exit the exhaust system. They go through the muffler which is supposed to make the exhaust quiet and exit the system all together. Some car enthusiasts will change the muffler to allow more airflow, or to even make the exhaust louder. The exhaust can only legally be a little louder than factory.
