An upstream air injection point, ahead of the catalytic converter, is also sometimes present to provide additional oxygen only during the engine warm up period. 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.
You can also add other upgrades to give your Charger an extra performance boost. Visit the AmericanMuscle headers and exhaust accessories pages to find parts that fit your new cat back system. Mishimoto offers a wide selection of exhaust systems, including cat-back exhausts, performance exhaust systems, and aftermarket exhaust options, designed to enhance your vehicle's performance, sound, and style.
