Exhaust system (Mercedes-Benz S-Class W116)

Removing and installing the exhaust system is not difficult, as all fasteners are clearly visible. When performing work, the following is recommended:

Rubber parts in good condition can be used for reinstallation. Do not hang exhaust system components under tension on rubber rings, as the rings will quickly break.

If the connections are difficult to unscrew, use anti-corrosion agents, after their use it is necessary to wait for some time. Then the nuts are easy to unscrew.

When connecting parts of the exhaust system, pipes, muffler, etc., ensure that they are located at the greatest possible distance from other parts of the car. After installation, start the engine and check the system for leaks, noise, etc. malfunctions.
