In general we can define the exhaust as the set of tubes that serve to channel the combustion gases of the engine outside the vehicle.
But in particular, each part also fulfills a very important specific function.
So the first part we find after the engine exit is the catalyst. Its function is to neutralize and transform the noxious gases produced by combustion (hydrocarbon, carbon monoxide and nitrogen oxide) into less polluting and environmentally aggressive substances. Then we find the silent intermediate that reduces both the speed and the temperature and pressure of the gases in the first phase. Finally, the silent rear reduces the noise of the gases expelled to an acceptable level whenever the temperature and speed of the gases fall in a second phase.

Exhaust deterioration may be caused both by the impact of objects and obstacles on the road, as well as by internal corrosion (defective ignition) or external corrosion (saline or humid environments), or engine vibrations that can cause breakdowns of the exhaust system.
The consequences of a bad escape are:

1. Engine power loss
2. Increased fuel consumption
3. Environmental pollution
4. Risk of penalties for exceeding acoustic levels

All systems in a car work interconnected. For this reason a problem in the exhaust system has harmful effects on the calibration of the gas emission control system. A small mismatch in the exhaust can cause a bigger problem and therefore a higher cost of repairing it. This is why the whole exhaust system needs to be maintained and maintained in good condition.

To avoid premature deterioration of the exhaust, the short runs should be reduced as much as possible, as they cause the accumulation of acids that favor internal corrosion. Also, in areas with very saline environments or in mountain walks in winter, it is advisable to clean the basins of the vehicle to stop external corrosion. Also avoid abrupt accelerations with the cold engine as well as starting by pushing the vehicle.

At each oil change includes an exhaust check that ensures that no problems arise until the next visit. Despite this, if the exhaust is detected to make a higher than usual noise, you feel metallic beating on the underside of the car on bad roads, you notice power loss and the vehicle drowns, or you have hit under the vehicle, to avoid more serious problems, do not hesitate to ask for a (free) check to make a diagnosis and repair or replace the defective part.
