General description of the exhaust system (Hyundai Elantra J1)

The exhaust manifold is mounted on the cylinder head. It continues with the front exhaust pipe. Next comes a small pre-muffler (resonator) or catalytic converter, and a final muffler. All elements of the exhaust system are connected using bolts. For repairs, all parts are available for sale separately.

Service life of the exhaust tract

The rate of exhaust gas corrosion decreases as exhaust gas temperature decreases. From this point of view, short-distance trips with stops and engine cooling are less harmful than long-term driving with a warm engine and constantly hot exhaust gases. However, when cooling, condensation forms in the mufflers, which, when mixed with combustion products, forms aggressive acids that corrode the metal of the exhaust tract from the inside.

Elements of the exhaust system of models with a catalytic converter (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. Hitting rocks or driving over uneven surfaces also shortens the life of the exhaust system, as well as vibration caused by defective suspension rubber or poor engine mounting.

Exhaust system components for models with catalytic converter (since 2000)
1 - front pipe;
2 - oxygen sensor;
3 - heat shield;
4 - central muffler;
5 - rear muffler.
