How Does an Exhaust Valve Work?
An exhaust valve is designed to release burned gases from a cylinder. The exhaust valve will open or close depending on if it is an electronic valve or a remote-controlled valve and also depending on the engine size and manufacturer. The opening of the valve will allow for more exhaust flow through a secondary exhaust pipe allowing the engine to breathe more, producing more overall flow as well as sound and performance. The exhaust valve is not a required component of the exhaust system but is very helpful in allowing you to control the amount of exhaust flow as well as the sound and performance. Many performance vehicles come from the factory with a valve exhaust system as these high-performance engines benefit from the ability to control the exhaust flow. Often, the vehicle will have an electronic system which automatically opens and closes the valves depending on the RPM or speed of the engine. This is to allow for maximum performance of the engine when the eng...
