In case of small holes in the sheet of which it is made, there are special heat-resistant mastics available on the market or in the case of larger holes, special glass fiber bandages impregnated with a thermosetting compound.

In these cases, proceed as follows:

1. Take the car over the mechanic's hole or on the bridge.

2. Degrease the affected area with petrol and clean it very well.

3. Now apply the mastic with the help of a spatula

4. If the hole is large, wrap the bandage and secure it with wire to hold it in place until it has completely hardened.

If, on the other hand, the situation is so serious as to completely replace the muffler:

1. We unscrew the cable ties

2. We spray release oil on the joints, rust tends to weld them

3. Let the unlocking agent work for a while

4. We can now install the new component.
