The catalyst is the most expensive part of the entire exhaust system of a car, but the vast majority of modern specialized service centers can solve the problem by installing universal catalysts in car mufflers. This allows you to reduce the cost item for the current repair of catalysts, since there is no need to look for and install an expensive, original spare part, the prices for which can be quite high. In some cases, it is possible to replace the automotive catalyst with a flame arrester.
In addition to the catalyst, the car muffler is equipped with a corrugation to compensate for temperature differences and fluctuations that occur during engine operation. The corrugation often burns out or breaks in case of blows. It is quite difficult to change the corrugation on your own, it also does not make much sense to buy a new similar part – in specialized workshops this muffler element is quickly and relatively easily replaced with a new one.
The exhaust system as a whole, and in particular its metal components, are highly susceptible to corrosion and vibration, which in most cases leads to malfunctions in the operation of the muffler and resonator. This is facilitated by the fact that the exhaust system is located at the lowest point of the bottom and is coupled with the engine of the car. In this configuration, the possibility of various mechanical damage is very high, especially for the corrugation and the suspensions that support it.
If it is necessary to repair the exhaust system of a car, the best option would be to completely replace it, but this option is not always possible, since the purchase of a muffler for some models is a rather big problem. In such a case, only repairs can help. Usually, when repair work is necessary, the muffler is removed, which greatly simplifies the whole process. Before choosing a service for repairing a muffler, it is worth asking about the quality of the proposed repair work.
