If the sound of the engine is more loud and sharp, it means that the integrity and integrity of the silencer must be checked. And the silencer does not always need to be replaced-sometimes it can be repaired. At the same time, it is not necessary to use traditional welding to repair the silencers.

Cold welding is an excellent alternative to conventional electricity. The cold welding is a special sealant which quickly freezates and is not exposed to the adverse effects of petrol, oil and other technical fluids. There are two types of silencer: liquid and plastic. If a liquid seal is used, it will also need a glass-cloth, which is soaked in liquid sealant and serves as a patch. Plastic sealants are like clay that needs to fill a hole in a silencer. Before delivering a plastic sealant or "patch", the silencer must be cleaned from the dirt and degreasing the surface with an anti-silicon or petrol. It is necessary to work with liquid and plastic sealants quickly, as they will start to stimle within a few minutes. The time of total drying depends on the specific sealant that you use, as well as environmental conditions. To understand how long it will be to dry the sealant on the silencer, you should carefully examine the instructions for the repair. To check whether the silencer has been repaired, it is necessary to have a car and let it work at idle for half an hour. Replacement of burnt silencing insulation

Another widespread damage to a silencer is a exhaust bank that can also be repaired by its hands. This will require special insulation material. A resistant linen is just stuck around the silencer to absorb the loud sound of the exhaust. The noise level will, of course, be higher than that of a fully functional silencer, but it is possible to delay the repair in such a way. Some drivers are sure that the repair of the silencer is optional. Supposedly, there is no inconvenience except loud noise from it, and the roar of the engine can be ended. In fact, this is not the case: the defective exhaust system leads to the reduction of the engine efficiency of the engine, as well as to an increase in the negative impact of the vehicle on the environment.
