What is an exhaust system?
The exhaust system must deliver dangerous gases from the engine to a safe exit point at the rear. Any escape of these gases into the vehicle can be potentially fatal to the occupants.
The catalytic converter reduces the exhaust gas pollutants released into the atmosphere while the muffler and resonator reduce the level of noise omitted.
Why do mufflers rust?
Inside the muffler a variety of corrosive gases and acidic soups attack the metal interior under extreme temperatures. Chemical corrosion is caused by oxidation, cold condensate and the presence of acids associated with internal combustion.
The quality of the fuel, presence of additives, air - to - fuel ratio, engine setup and efficiency of the catalytic converter all effect the life of a muffler. As it accumulates, the acidic soup begins to attack the interior surfaces of the muffler.
Your driving habits, the exhaust design, climate temperature, humidity and contact with salt are all reasons why mufflers rust and need replacing.
