Exhaust system used until July 1979
The twin exhaust pipe leans with six nuts to the elbow of the engine exhaust pipe. This pipe directs the exhaust gases, which initially go through two pipes, into one. Next comes the bellows. This is a short tube that needs to be flexible to dampen the vibrations of the exhaust system. Next comes the pre-muffler. Despite the presence of a clamp at the muffler, it does not separate in this place. The main muffler is connected using a fork connection.
Instruction. At the bend of the pipe of the main muffler there is a suspension strut, consisting of two tubular brackets and a movable connecting rod. This seemingly useless part protects the exhaust pipe from cracking in this place as well. Therefore, it must be installed. when the pipe is changed.
Exhaust system used since August 1979
On newer models, the exhaust system looks a little different. The front exhaust system has another channel. To avoid rattling and breakage, the coarse is attached to the elbow of the engine exhaust pipe using two clamping springs. Removing the pipe requires a special tool (see section "Removing the front exhaust pipe"). This is followed by the preliminary and main mufflers. There is no bellows in this system, as well as the bracket of the first muffler. The suspension strut is also no longer used.
Exhaust system life
The service life of the exhaust system may vary. Durability depends on the operating conditions of a particular vehicle. If the car mainly drives on short routes, then the output of condensate, soot, sulfur and aggressive acids inside the muffler is much greater. The exhaust pipe is rusting from the inside. Continuous driving on long highways at full operating temperature and more favorable combustion reduces the content in the exhaust gases of components that cause corrosion. In addition, the exhaust pipe always burns due to higher operating temperatures. Rust appears due to splashes of water and salt, which are scattered on the roads in winter.
