What Is the Purpose of a Resonator?

There's a lot you can learn about the purpose of a resonator – it's more than a random pipe funneling exhaust gases through your system. So, what does a resonator do on an exhaust system? A resonator's purpose is to modulate and change your exhaust note, fine-tuning it into a more organized pattern. Essentially, an exhaust resonator acts as a large echo chamber.

By manipulating the frequency of sound waves, an exhaust resonator removes high-pitched noises and annoying hums and buzzes for a smoother exhaust note. While it doesn't affect the volume, exhaust resonators are perfect for reducing noise and drone together with the muffler, making cruising speeds better for the driver and passengers. If car owners are experiencing drone within a specific RPM range, an exhaust resonator can help correct it.

Additionally, exhaust resonators play an essential role in the exhaust evacuation process, helping your engine produce more power and reduce fuel consumption.

How Does a Resonator Work?

Not all exhaust resonators are designed the same way. However, all contain some form of sound-dampening material wrapped around perforated tubes of carefully chosen lengths and diameters.

Primarily, the resonator in a car works based on something called destructive interference – the same technology found in noise-canceling headphones. When high and low-pitched sound frequencies hit an exhaust resonator, they bounce off the outer walls (resonating), canceling out higher, more annoying tones to eliminate exhaust drone. Additionally, this makes the job of your muffler easier without robbing you of any efficiency or power from the engine.

Ideally, a resonator is designed to work in frequency ranges where the engine makes the most noise. However, even if the frequency is not precisely what the resonator was tuned for, it still can produce some destructive interference.

What to Consider When Purchasing an Aftermarket Exhaust Resonator

If you're thinking about installing an aftermarket exhaust resonator, there are a few things you'll want to keep in mind to ensure the best results.

  • Size: Aftermarket exhaust resonators can be purchased in different diameters and tube lengths – they are not one-size-fits-all components. The size you want will depend on the type of exhaust system you have installed in your vehicle. Be sure to accurately choose a resonator with an inlet and outlet diameter compatible with your muffler.
  • Material: The material used on an exhaust resonator is essential to its longevity and overall performance. If you find an aftermarket resonator designed from long-lasting and durable material, like 304-stainless steel, it's worth the investment. Because a resonator in a car will be located close to the ground, you'll also want to ensure the material is resistant to corrosion and rust.

Tips for Exhaust Resonator Installation

If you're considering installing an aftermarket exhaust resonator in your car, you have a few options. You can either take it to a professional or get it done independently. If you're a DIYer through and through, there are a few things to keep in mind during the installation process. Here are our best tips for DIY exhaust resonator installation:

  1. Work in a well-ventilated space to prevent excessive buildup of exhaust gas in your garage or work area.
  2. Remember that components under your car will be hot if you've been running it for an extended period. Allow things to cool before resuming work.
  3. Some exhaust resonators are weld-in components. Ensure you're always wearing the proper safety equipment to avoid accidents.
  4. Don't ignore a sound, smell or performance issue once the exhaust resonator is in. Any of these are indications it was not installed properly and could cause future maintenance issues.
