Heat, pressure and noise- these are some of the major concerns managed in the engine and exhaust systems. As two of the most important systems in your vehicle, the engine and the exhaust should keep these three elements from affecting the normal vehicle processes. These two systems are basically responsible for the handling of gas, starting from the raw form to the emission form. The transition of gas properties involves so many processes which can have bad effects to the two systems.
Your BMW 5 series exhaust system is assembled with a series of boxes, pipes, and other devices channeling emissions from the engine out to the atmosphere. Particularly, the most important among these assembly parts are the turbo charger, catalytic converter, exhaust pipes, exhaust manifold, and silencer. Exhausts need to efficiently provide four basic functions - to channel exhaust fumes away from the passengers; to regulate the noise; to provide the highest possible engine efficiency and to improve fuel mileage. The exhaust system really has significant responsibilities. Hence, proper care and maintenance are just important. Just imagine how it will perform once any of the exhaust components is taken for granted. The most possible products of bad exhaust components are the toxic gases escaping to the atmosphere and the relatively low engine performance.
Under extremely high temperature and pressure, corrosion is always possible. The most frequently damaged exhaust part is the silencer. This device is the farthest exhaust part from the engine and is exposed to gases coming in and out of the vehicle. Silencers may contain acidic moisture because of the pressure and temperature changes. The corrosive acid will precipitate in the silencer as it remains relatively cold. This will damage the silencer, which will later be manifested by an annoying noise. Nevertheless, noises are not just brought by bad silencer because some cracks on the exhaust manifold and exhaust pipe are also possible to take place. Also, a leaking gasket may cause hissing sound while a chugging noise is a sign of blockage in the system. If any of these signs become evident in your BMW 5 Series exhaust, then check out the components that may be in need of immediate replacement.
