Service life of the exhaust tract
The rate of corrosion from exhaust gases decreases as the temperature of the exhaust gases decreases. From this point of view, short distance trips with stops and engine cooling are less harmful than long trips with a warm engine and constantly hot exhaust gases. However, when cooled, condensate forms in the mufflers, which, mixing with combustion products, forms aggressive acids that corrode the metal of the exhaust tract from the inside.
Elements of the exhaust system for models with a catalyst (before 2000)
1 - front pipe;
2 - oxygen sensor (front);
3 - oxygen sensor (rear);
4 - catalyst;
3 - heat shield;
6 - central muffler;
7 - rear muffler.
Regardless of the driving mode, moisture entering from the outside causes rust. Stone hits or bumps will also shorten the life of the exhaust tract, and with them the vibration caused by defective suspension rubbers or poor engine suspension.
