You might be asking, is there such a thing like a quiet performance muffler? Well, in this guide, I’ll be reviewing some of the quietest high-performance mufflers you can get on the market today.
Mufflers play an important role in a car’s exhaust system. They are designed to reduce car noise. In most states, it’s a legal requirement to have car mufflers. (Source) This helps in significantly reducing excessive or unusual noise and smoke. There’s more than meets the eye when it comes to choosing a muffler for your car. The muffler you choose will alter the way your car sounds; some will offer a deep growl while others will make your car as quiet as possible.
Straight through vs. chambered vs. Turbo: which one is the quietest?
Like I earlier stated, a muffler design will determine how quiet and how noisy the muffler is. Let’s have a look at the various design and how quiet or loud are.
· Straight-Through/ Glasspack
As its name suggests, Glasspack mufflers are packed with sound-dampening materials such as steel wool or fiberglass, which are good sound deadening products. They have a packing that’s wrapped around a perforated pipe. This pipe-which is straight- allow gases to flow smoothly without being backed up hence giving maximum horsepower, which is great for racing.
Glasspack designs make the best performance mufflers. However, they are often loud, which could be a disadvantage when you’re looking for a quiet muffler.
Unlike straight through, chambered mufflers create a deep sound which is quieter. They have a series of inner chamber that bounces sound waves around so that some waves end up canceling each other out.
It’s pretty easy to alter the sound produced by chambered mufflers by adjusting the shape and the size of the inner chambers. These are great for muscle and streetcars.
The turbo types combine the technology used in both chambered and Glasspack. They work by channeling gasses through S-shaped tubes which have sound dampening materials applied around them. While they have more pressure on the system than the two above, they make for a quieter running engine.
How does a quiet muffler work?
All mufflers are designed to alter the noise your car emits- typically making the car quieter. How a muffler will work depends on whether you choose chambered design or glass packed design, but both works to reduce the noise emitted in one way or another.
These mufflers utilized destructive interference (Source). As the sound waves travel through the component, they are forced to bounce through strategically placed chambers which direct them in such a way that some waves cancel each other out.
This means that only a few sound waves end up emitted from the exhaust system, and hence, the sound emitted is quieter. The chambers and tubes inside chambered mufflers can be altered to alter the sound emitted.
These have the simplest design. They are packed with sound-deadening materials in most cases fiberglass, but at times, steel wool is used. The sound-absorbing material suppresses the sound as it moves through the muffler system. (Source)
