The internal combustion engine makes noise. Even a small sedan can make so much noise, enough to disturb passengers, Mufflers reduce the noise coming from the exhaust system. They attach to the tips of the exhaust system just where the exhaust gas comes out. When attached right, these mufflers reduce the sound levels coming from the exhaust system. If you do not pick the right system, they might result in back pressure that causes the engine of your vehicle to work harder.
Performance mufflers reduce the noise while also keeping back pressure low to keep the engine in top shape. These mufflers are customized for specific vehicle make, model, and year. Most mufflers come with directional arrows that show you how to install them the right way. In some countries, it is illegal to drive around without an exhaust muffler, and even if it is not illegal, it is advisable to have a muffler.
