It is necessary
- - grinder;
- - welding machine;
- - muffler;

Instructions
Step 1
Try to understand the nature of the changed exhaust sound. To do this, press the accelerator pedal several times with the engine running. It is better to ask someone of your acquaintances to talk to you so that you can listen to the sound on the street.
Step 2
Pay attention to whether water is dripping from the exhaust pipe. If fluid continues to ooze even after fifteen minutes of engine operation, the exhaust system is malfunctioning and needs to be repaired.
Step 3
Drive the car onto an overpass or pit. It is best to go to the nearest car service and lift the car on an electric lift. Examine the muffler carefully.
Step 4
It is necessary to carefully check the place where the muffler is inserted into the manifold. The reason may be a depressurized adapter. In this case, replace the rubber gasket and re-weld the muffler to the manifold.
Step 5
Check all fasteners. Loose ones must be replaced with new ones. It is best to use aluminum or plastic clamps as fasteners. Attach the muffler carefully along its entire length.
Step 6
Examine the underside of the vehicle. Abrasions indicate that the muffler is touching the body. In these places, you need to put a rubber gasket, lubricating the metal with an anti-corrosion compound.
Step 7
Remove catalysts if you want to give your car a deep, sporty sound. To do this, dismantle the muffler. Find the place where the catalysts are installed. Make cuts with a grinder. Remove the catalytic converter housing. Weld the cut piece back on.
Step 8
Install a special nozzle on the muffler if you do not want to make any technical changes. These nozzles are inserted into the end of the pipe. There are small propellers in the middle of this nozzle. They start to twist quickly and make a sound when the exhaust gas is ejected from the pipe. The nature of the sound depends on the number of blades and the location of the nozzle.
