Exhaust Resonator
A resonator is an exhaust silencer section that cancels specific sound frequencies, such as drone at cruising speed.
What is Exhaust Resonator?
It works together with the main silencer. It is often a straight-through design. Removing it changes the exhaust sound. Manufacturers place resonators to tune the sound inside the cabin as well as the outside noise. Aftermarket replacements should keep sound levels within legal limits.
How it works
Chambers tuned to certain frequencies reflect sound waves so they partly cancel each other.
Why it matters for your car
Rusted resonators can leak or rattle. Removing them can cause loud drone and may break noise rules.
