Between the catalytic converter and the additional muffler...
... and also between the additional and main silencers there are special marks, in the middle between which it is necessary to cut the system to replace the elements of the exhaust system. On sale there are special crimp couplings for connecting the installed elements of the system.
The system has an exhaust gas catalytic converter. To protect the base of the body from heating by the elements of the system, thermal screens are installed above the converter, the main and additional mufflers, as well as near the fuel tank.
The elements of the system are suspended from the body on three rubber cushions.
The exhaust system does not require special maintenance. It is enough to periodically check the reliability of the tightening of the threaded connections and the integrity of the suspension pads. In case of damage to the elements of the system, through corrosion or burnout, they are replaced as an assembly.
Note. Periodically check the exhaust system. If there is an increased noise level from the exhaust system, check its tightness. To do this, start the engine and inspect the entire system. By running your hand over the places of a possible leak, without touching the nodes, you will immediately feel the leakage of gases. If necessary, replace rusted and burnt parts.
Warning! Allow the exhaust system to cool before repairing, as the exhaust system becomes very hot when the engine is running. Exhaust gases are poisonous, their poisoning occurs imperceptibly, so be sure to open the gate before starting the engine in the garage!
Note. If it is impossible to replace the defective unit with a new one, you can temporarily restore its performance by applying a metal patch to the damaged area and securing it with clamps or wire. It is recommended to place a sheet of asbestos under the patch. In addition, auto parts stores sell special kits for rebuilding exhaust system components, with which you can temporarily repair damage to the system in order to get to a car service or garage.
