Buying Guide for The Best Mufflers for V6

A muffler, as mentioned earlier, is a straightforward component. But what goes inside the muffler can overwhelm you if the entire process is brought in front of you. But that’s not our aim today.

Instead, we are going to reveal the secrets of choosing the most appropriate muffler for your vehicles, especially those equipped with a powerful V6 engine.

So, let’s get to see it.

Muffler Design and Type

The design of a muffler, along with its type, largely decides its performance sound output. So, you need to determine which muffler type you want for the vehicles.

There are three types of muffler vehicles consumers will find in the market. These are:

  • Glasspack muffler: This type of muffler has a fiberglass-made interior. The majority of the gas is emitted straight through the muffler. That’s why it gets the name straight through as well. It has the loudest sound with the maximum airflow.
  • Chambered muffler: It is a mid-range muffler in terms of noise level. Although it is quieter than the glass pack, the muffler is still capable of producing a pleasing and aggressive sound tone. It can manipulate the sound frequency, which makes it an ideal alternative for muscle cars.
  • Turbo muffler: It is a combination of chambered and straight-through mufflers. While the channel emits gases, its chamber and fiberglass filter them for better exhaustion and pleasing sound notes.  It is the quietest muffler in the industry.

Mufflers often encounter debris, high temperatures, and extreme pressure on the road. So, they need to be made of durable materials.

The stainless steel mufflers have high rust and weather-resistant capacity and are preferable for powerful and large vehicles.

Fitting Requirement

It is probably needless to say that your purchased muffler should fit the car’s existing system. The fitting is dependent on many factors. For example, you need to see whether your vehicle is a single or dual system.

Also, you need to check the diameter of the exhaustion outlet and room for the muffler.

The Sound You Want

You should, by this time, understand that sound production is linked with the muffler type. So, make your selection accordingly.

Mufflers make a vehicle operate quietly by altering the noise emission. For instance, a glasspack muffler has sound-absorbing material such as wool or fiberglass that dissipates the sound. The chambered muffler does the same with multiple tubes that manipulate the sound output.
