Chevy Mufflers
If your Chevy car engine is running without a muffler, you know what a huge difference
a muffler can make to the noise level. Also known as a “backbox” or “secondary
muffler”, a muffler is a part of an exhaust system. It is usually located near
the rear of a car. The muffler is designed to decrease the volume of the exhaust.
The body of the muffler is constructed in three layers: two thin layers of metal
with a thicker, slightly insulated layer between them. This allows the body of
the muffler to absorb some of the pressure pulses. Also, the inlet and outlet
pipes going into the main chamber are perforated with holes. This allows thousands
of tiny pressure pulses to bounce around in the main chamber, canceling each other
out to some extent in addition to being absorbed by the muffler's housing.
There are other features inside the muffler that help it reduce the sound level
in different ways. A basic muffler consists of a series of metal plates or tubes
with multiple holes. The holes put pressure against the exhaust flow and decreases
the noise. Chambers exist between the metal plates to ensure the flow of the exhaust.
A high-performance muffler contains a single, large pipe with holes along the
side. This reduces the sound a little, but it rarely puts pressure on the exhaust
and allows it to flow freely.
Chevy mufflers use some pretty neat technology to cancel out the noise. A chamber
called a resonator is attached to the first chamber by a hole. The resonator contains
a precise volume of air and has a specific length that is calculated to produce
a wave that cancels out a certain frequency of sound. In reality, the sound coming
from the engine is a mixture of many different frequencies of sound, and since
many of those frequencies depend on the engine speed, the sound is almost never
at exactly the right frequency for this to happen. The resonator is intended to
work best in the frequency range where the engine makes the most noise; but even
if the frequency is not exactly what the resonator was tuned for, it will still
produce some destructive interference.
Another one important characteristic of Chevy mufflers is how much backpressure
they produce. The muffler is a key to the performance of the car because the more
muffler decreases the sound, the more backpressure it creates on exhaust flow.
And increased backpressure means decreased performance.
Your Chevy car deserves the best Chevy muffler. You can choose from the sites
in the internet the best Chevy muffler you are looking for. From the basic Chevy
mufflers to the high performance Chevy mufflers, it’s all there. |
