Between the catalytic converter and the additional muffler...
...and also between the additional and main mufflers there are special marks, in the middle between which it is necessary to saw the exhaust system to replace its elements. Special compression couplings for connecting newly installed system elements are available for sale.
The system has a catalytic converter of exhaust gases. Above the converter, the main and additional mufflers, and also near the fuel tank, heat shields are installed, which serve to protect the base of the body from heating by the system elements.
The system elements 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 tightening of threaded connections and the integrity of suspension cushions. In case of damage to system elements, through corrosion or burnout, they are replaced as a whole.

Helpful tips:
Check the exhaust system periodically. If the exhaust system is noisy, check for leaks. To do this, start the engine and inspect the entire system. Run your hand over the possible leaks without touching the components, and you will immediately feel the gas leak. If necessary, replace rusted and burnt components.
If it is impossible to replace the defective unit with a new one, you can temporarily restore its functionality by applying a metal patch to the damaged area and securing it with clamps or wire. It is recommended to put a sheet of asbestos under the patch.
In addition, auto parts stores sell special kits for restoring exhaust system components, which can be used to temporarily repair damage to the system in order to get to a car service center or garage.
Warnings:
- Allow the exhaust system to cool before repairing it, as it reaches high temperatures during engine operation.
- Exhaust gases are toxic, and poisoning occurs unnoticed, so be sure to open the garage door before starting the engine!
