A muffler is also known as a silencer. It is part of the exhaust system where it attaches to the tips of the exhaust system. When attached, the muffler reduces the noise that comes from an internal combustion engine.
These devices should install within the vehicle’s exhaust system. Once installed, the muffler reduces the sound pressure that comes from an internal combustion engine through the exhaust engine. This process is known as acoustic quieting.
A muffler contains passages and chambers with fiberglass for insulation. In some instances, restricting the flow of gas might cause back pressure, which can affect a vehicle’s fuel efficiency. You can go for aftermarket performance mufflers that reduce noise and also reduce backpressure to keep the gas mileage intact. However, some of these mufflers that reduce back pressure might offer less noise reduction, meaning you will have a high gas mileage, but vibrations and noise remain.
