How to Reduce Exhaust Noise and Exhaust Drone (Explained)

Updated: Jan 9

Exhaust noise and exhaust drone can be an annoying and even a harmful aspect of car ownership. These issues can be caused by various factors, including the design of the exhaust system, the type of vehicle, and the type of engine.


In this article, we will discuss what exhaust droning is, how to reduce exhaust noise and exhaust drone, and whether resonators can help reduce these issues.

What Is Exhaust Droning?

Exhaust droning is a low-frequency noise that is produced by the exhaust system of a vehicle. It is often described as a "booming" or "rumbling" sound that can be heard inside the car and sometimes even outside the car.


Exhaust droning is typically caused by the vibrations of the exhaust system, which can be caused by a variety of factors such as the size and shape of the exhaust pipes, the type of muffler, and the type of engine.


Will a Muffler Delete Cause Drone?

A muffler delete, also known as a back box delete, is a modification to a vehicle's exhaust system in which the muffler is removed and the exhaust pipes are connected directly to the exhaust manifold or header.


Muffler deletes are often done for performance reasons, as they can increase the flow of exhaust gases and potentially improve the power output of the engine. However, muffler deletes can also cause an increase in exhaust noise and potentially lead to exhaust drone.


Removing the muffler can cause an increase in exhaust noise and potentially lead to exhaust drone.


However, the extent to which a muffler delete will cause these issues will depend on various factors, such as the design of the exhaust system, the type of vehicle, and the type of engine.


Some muffler deletes may produce more exhaust drone than others, so it's important to do your research and consider the potential consequences before making this modification.

If you do decide to go through with a muffler delete, it's a good idea to consider installing a resonator or using a different type of exhaust system in order to help reduce exhaust drone.


How to Reduce Exhaust Noise and Exhaust Drone

There are several ways to reduce exhaust noise and exhaust drone, including the following.


  1. Use a muffler: A muffler is a device that is designed to reduce the noise produced by the exhaust system. There are various types of mufflers available, including straight-through mufflers, chambered mufflers, and glasspack mufflers. Each type has its own set of advantages and disadvantages, so it's important to choose the right muffler for your specific needs.

  2. Install a resonator: A resonator is a device that is designed to cancel out certain frequencies of noise. By installing a resonator, you can reduce exhaust noise and exhaust drone, especially at certain RPM ranges.

  3. Use a different exhaust pipe size: The size of the exhaust pipes can have a significant impact on the noise produced by the exhaust system. By using a different size of exhaust pipe, you can change the frequency of the exhaust noise and potentially reduce exhaust drone.

  4. Use a different type of exhaust system: There are various types of exhaust systems available, each with its own set of characteristics. By using a different type of exhaust system, you may be able to reduce exhaust noise and exhaust drone.


Do Resonators Reduce Exhaust Drone?

Resonators can help to reduce exhaust drone, especially at certain RPM ranges.


However, it's important to note that resonators may not completely eliminate exhaust drone, and the effectiveness of a resonator can vary depending on the specific characteristics of the vehicle and the exhaust system.


In some cases, a resonator may need to be used in conjunction with other methods, such as a different muffler or exhaust pipe size, in order to effectively reduce exhaust drone.
