What does drone sound mean in exhaust?
Exhaust drone is an annoying, monotone sound and vibration that occurs in some aftermarket exhaust systems. It’s usually caused when the frequencies of the engine and exhaust are aligned at a certain RPM (typically 2,000-3,500 RPM). You’ll never hear exhaust drone in a car that uses the stock exhaust system.
Do straight through mufflers drone?
Straight-through mufflers will have the least amount of drone, as air swirl and turbulence are virtually non-existent. Some chambered mufflers have drone, but most of them have gotten a lot better as of recent.
What does drone sound mean?
a monotonous low tone; humming or buzzing sound. a person who speaks in a monotonous tone.
How can I reduce the sound of my muffler?
How to Quiet Exhaust Sound
- Replace the existing muffler.
- Install an exhaust tip with a sound dampening liner.
- Attach vibration dampening mats to the metal surfaces of the cabin and interior walls.
- Install a sound blocking material over the interior surface areas.
Why is my drone so loud?
The loud noise that drones produce comes from the fact that rotors are slicing through the air so we hear buzzing noise. When we talk about electric motors, they are very quiet by themselves; but when you use only a multirotor without its propellers on and all you’ll hear is a slight whine.
What does a muffler do to reduce drone?
It’s true that the primary job of the muffler is to lower your volume, not change the pitch or tone. However, there are also acoustic properties within the muffler itself. The baffles can change the frequency and affect drone. Your muffler will reduce overall exhaust volume, which can reduce drone.
What kind of exhaust sounds like a drone?
Drone is more common with a loud, low-frequency exhaust. This creates a hollow buzzing that can grate on your ears. Drone is also more likely to occur with track exhaust systems. These loud, performance-oriented systems are designed to give you a high-volume exhaust note.
Is there a way to prevent exhaust drone?
Mufflers or resonators in track exhaust systems won’t be as effective at preventing drone compared to stock. The resonator and muffler reduce exhaust drone. Not every aftermarket exhaust system is going to have drone. In fact, most don’t, and many are specifically designed to combat the phenomenon.
Where do you put a resonator on a muffler?
You need to attenuate the sound coming OUT of the muffler. Padilen likes this. I’d put the resonator at the back end of the tail pipe or at least after the muffler as that is where the drone originates. Putting a reso in front of it won’t help much.

What does a drone muffler do for a car?
Drone is that sound resonance inside the vehicle that can be described as a constant hum when driving at part throttle. Three chambered mufflers will add additional chambers with tuning tubes to help cancel out those frequencies.

What’s the difference between a resonator and a drone?
Some manufacturers show a “resonator” in front and a “muffler” at the rear but to be clear, what attenuates the sound coming from the muffler (which is what you are experiencing now from the Magnaflow aka drone) needs to be attenuated downstream from that box.
