Resonators
A resonator is an important component in the exhaust system installed between the catalytic converter and the muffler. It is cancels out certain noise frequencies in the exhaust system. Automobile sound engineers determine the frequency range that is not suitable to hear. They design resonators to eliminate these sounds. Typically, the sounds canceled out are harsh and irritating.

You should note that the resonator does not necessarily reduce sound. It only eliminated unwanted frequencies. When used in Mustang it makes the exhaust more aggressive and louder.
Some resonators are attached to the muffler. The muffler reduces the exhaust noise while resonator reduces the voice further by creating sound waves that cancel out noise. As a result, your car will produce pleasant and less annoying noise. A resonator is made of a steel tube.
When it comes to your vehicles exhaust system, the resonator has multiple jobs. They include:
1. Gas Pass
As the exhaust gases leave the engine combustion chamber the sound waves bounce on the walls of the exhaust pipes producing high and low noises frequency. Resonator acts like an echo chamber that optimizes the frequencies of the exhaust pulses to boost power production and fuel efficiency.
2. Tone setting
The resonator collects sound waves and tweaks them in organized patterns. This does not increase efficiency and power but gives you vehicle engine a distinctive sound. You must have noted that Ferraris or any other car has their signature sounds. This sound comes from the resonators.
3. Controlling exhaust gas flow
Combustion process partially involves pushing exhaust gas out if the combustion chamber and replacing it with fresh air. Modern combustion engine relies on resonators to use sound waves to empty the chamber and release exhaust gases through the pipes and muffler. It tunes exhaust gases pulse to work together and create stronger exhaust waves and hence evacuating gases faster.
4. Controlling sound volume
Resonators play a crucial role in controlling the sound volume that your car’s engine produces. It can, therefore, silence the sound or give it a throaty sound.
Replacing a Resonator
The main reason that would necessitate a resonator replacement is if you plan to install a custom exhaust system in your vehicle. In most cases custom resonators are designed for horsepower than noise reduction. They give the car engine a throaty sound suitable for performance cars.
Resonators are somewhat similar to mufflers. In fact, most people confuse resonators with mufflers. While they have some distinct function, they have several similarities including producing optimal engine sound and exhaust gases evacuation which aids in boosting engine power and fuel efficiency.
