Exhaust systems are undoubtedly the bowels of any vehicle, automobile, or aircraft. The main function of the exhaust system is to allow for the smooth propulsion of gas emission from an engine out to its surrounding environment. This allows for proper gas exchange to take place in order to optimize fuel usage and energy output. In theory, this function could be performed by any metal tubing that leads from the engine to the tailpipe, however, there are many other requirements that must be considered in order for an exhaust system to function effectively. According to Federal Aviation Association (FAA) regulations, the exhaust system of an aircraft must be able to withstand high temperatures, corrosion, vibration and inertia loads, and must have means for flexibility in addition to performing its typical roles.
