Types of Quiet Performance Muffler
There are three main types of performance mufflers- they are as follows:
These feature an internal mechanism designed to ensure that sound waves cancel each other.
They are most common because it’s easier to manipulate them to achieve the sound you want.
However, these are only great for muscle cars as well as streetcars and are much quieter compared to straight-through mufflers.
These have sound-deadening materials, which make them quite unique.
They use soundproofing materials such as fiberglass and steel wool that are installed on the perforated pipe to help absorb exhaust noise passing through it.
It’s important to note that the wrappings don’t interfere with the gas flow- so you still get the horsepower you want.
Unfortunately, even though they are fitted with soundproofing materials, they are not as quiet as the chambered counterparts.
Turbo mufflers are a modification of both chambered and straight-through mufflers.
They are designed such that they direct gases through several S-shaped tubes constructed from soundproofing materials.
Unfortunately, these types of mufflers are more demanding- they exert more pressure on your car.
