The muffler is necessary to reduce the noise generated by the exhaust gas stream, effectively blocking their path. And ideally, there should be no obstacle to the exhaust of gases from the cylinder.
Instructions
Step 1
To start combating the excessive noise generated by the car, launch an offensive on all fronts. Before taking decisive action, you must clearly understand the work of the exhaust system of the car engine. After all, the engine and exhaust system are balanced with each other so as not to interfere with each other's work. And a violation of this balance can lead to improper engine operation.
Step 2
Use the simplest method to reduce noise - install a "can" (as motorists call an additional final muffler). It is made of a body through which a pipe with holes passes. The body is filled with heat-resistant fiber filler fixed with a fine mesh. It is installed between the catalyst and the standard muffler.
Step 3
Cut a section of pipe between the catalyst and muffler to the required length, corresponding to the length of the "can". Remove the muffler. Install and attach the "can" to the resonator using clamps and asbestos sheet to seal the joint.
Step 4
Install the muffler in its original place, docking with the "can", using, again, clamps and sheet asbestos to seal the joint. When installing a "can" or final muffler, it is necessary to carefully seal the pipe joints with heat-resistant asbestos in order to prevent the breakthrough of exhaust gases, which will create an increased noise level.
Step 5
An additional effect on noise reduction will be given by the replacement of the resonator installed on the car by the manufacturer with the same "jar" with a heat-resistant filler. The replacement of the standard resonator can be carried out using the same technique.
Step 6
You can try another method of noise suppression - replace the exhaust manifold with a specially designed manifold. Unfortunately, this method is associated with the difficulty of acquiring such a spare part for certain car brands.
