Repair of a rusted exhaust system in most cases is of little success. If the metal is rusted, then it is so weak that it is impossible to perform welding work. Although the exhaust system is durable, the metal soon breaks near the repaired areas.
Very rarely both mufflers need to be replaced at the same time. If one muffler is replaced, then after a few months, unfortunately, the second one fails. For this reason, the workshops change the entire exhaust system at once. But we do not recommend doing this without prior verification. Verification is carried out as follows.
Thoroughly, in all places, tap the dismantled, but still serviceable muffler with a hammer. Hit harder.
If at each blow a sonorous sound is heard (high) sound, it means that the metal is still "healthy".
If the sound in some places becomes muffled, then this indicates that the outer shell has already weakened and will soon break, especially at that time of the year when salt is scattered on the roads.
When repairing, replace old fasteners with new ones.
Old, weakened rubber holders are also replaced.
