The exhaust system is a set of parts that prevent harmful chemicals from reaching into your car's engine and its combustion process. It mainly purifies the fuel, effectively reducing the level of noise and emissions. Clean fuel also increases a car's gas mileage.

Your exhaust is made up of the manifold, mufflers, resonators, valves, and the pipes. The manifold sorts out the chemicals as the muffler and resonator help with the sound. As the valves keep the ratio of air and fuel flowing into your engines, the muffler and resonator would then muffle the sound they make. Lastly, the pipes move across your engine to dispose of the used air and fuel combination behind the car.

All of the indicated parts don't have a particular maintenance schedule, though you'll have to pay attention to the fuel filters. Each part is replaceable with a different size, material, and budget depending on a driver's taste and how it might fit into the rest of your car.
