More on Exhaust Systems from OC Diesel

A vehicle's exhaust system is used to extract the toxic or polluting fumes that are byproducts of burning gasoline. These systems are typically composed of pipes, catalytic converters, mufflers, and a resonator. You can usually see the exhaust system on a truck, with a silencer surrounded by a metal sheet with perforations in order to safeguard anyone who may be standing near the component from being burnt. This sheath is typically chrome plated, because face it, chrome is sweet. A segment of the pipe which connects the engine and silencer is typically fabricated from industrial ducting made from flexible metal. This prevents engine vibration from damaging the rest of the exhaust system. Many larger diesel exhaust pipes are vertical rather than horizontal, which assists by blowing the gases away from people nearby. The tip of this often possesses a metal flap to protect it from small objects which can fall inside. The cat back, an easily recognized segment of the exhaust system runs from the catalytic converters' outlet all the way to the final vent in open air. These usually make use of a pipe larger in diameter than that of a stock system, and utilize glasspack mufflers to increase performance by reducing backpressure.
