It runs from the muffler to the back or to the side of your vehicle. They effectively reduce back-pressure by preventing exhaust gases from building up on either side of the system, which is highly likely in the absence of crossover pipes.Ī tailpipe is the last component of an exhaust system. Mufflers help reduce the exhaust noise by utilizing a combination of baffles, chambers, perforated tubes, and sound-deadening materials.Īpplicable only for dual-exhaust systems, crossover pipes are downpipes that help reduce uneven exhaust flow. When exhaust gases flow through these, they react with the coating and get converted to nitrogen, carbon dioxide, oxygen, and water. A catalytic converter typically consists of two ceramic honeycomb-shaped meshes coated with rare and precious metals. The computer then regulates the amount of fuel needed to achieve maximum fuel and combustion efficiency.Īlso known as head pipes, downpipes are metal pipes that help link the headers to the catalytic converters and mufflers of an exhaust system.Ī catalytic converter is the most important component of an exhaust system as it is responsible for reducing and converting extremely toxic and harmful emissions into less toxic gases before releasing them into the air. With that in mind, I am excited to present to you, the list of The Cinemaholic’s 100 Best Movies of All Time.Before you go on to start exploring our list of top 100 movies ever made, let’s remind ourselves again, that lists by their nature are never perfect. They help detect the amount of oxygen present in the exhaust gases and transmit the information to the vehicle’s onboard computer. Oxygen sensors are an integral part of any exhaust system. Depending on the number of cylinders, headers come in either a 3-into-1 or a 4-into-1 configuration. This allows the gases to flow freely, thereby reducing the back-pressure. They are bolted onto the engine’s cylinders and are usually mandrel-bent to minimize exhaust restriction. Mathilda May - Lifeforce (1985) When the guard in the military hospital gasps into his radio, 'you'll never believe what I'm looking at. Briefly explained below are the different components that comprise an exhaust system.Įxhaust manifolds, also known as headers, are the first piece of an exhaust system. 10 Actresses Who Are Basically Nude For The Entire Movie.
