This causes unburned fuel to ignite in the exhaust tract, thereby preventing it reaching the catalytic converter at all. This technique reduces the engine runtime needed for the catalytic converter to reach its "light-off" or operating temperature. Many vehicles have a close-coupled catalytic converter located near the engine's exhaust manifold. The converter heats up quickly, due to its exposure to the very hot exhaust gases, enabling it to reduce undesirable emissions during the engine warm-up period. + +The first widespread introduction of catalytic converters was in the United States automobile market. The exhaust system is crucial to a car’s performance, especially the catalytic converter which can go bad if it’s overworked. A stock exhaust system strives to minimize the car’s materials while maximizing space. This means that the exhaust system’s performance can suffer, having to work harder with less horsepower. + +When used in the context of aftermarket parts or performance upgrades, "cat-back" is used to indicate which section of the exhaust system the parts replace. Cat-back systems are available as both single- and dual-exhaust. All Thermal R& \ No newline at end of file
