Helmholtz
You may be wondering what the small tube on our Resonator Delete is? The small tube is a Helmholtz resonator. In an exhaust system, a Helmholtz resonator is a container of gas (usually air) with an open hole (neck or port) leading into the resonator. The volume of air/gas in and near the open port vibrates due to the 'springiness' of the air/gas inside.
A common example is an empty bottle: the air inside vibrates when you blow across the top of it!

What is Drone?
Drone is a point where the exhaust note resonates in the cabin, creating a noise that most drivers dislike. This is why we have created Anti Drone Resonator Deletes.

When removing the standard resonator, you are paying the difference between someone who wants to give you a pipe and throw it on the car, and a company that has designed a product for a specific job, taking the time to research, develop, and test to make the product the best it can be!

RPM PERFORMANCE Anti Drone Resonator Deletes have been designed to reduce drone throughout the rev range, specifically at motorway speeds on UK roads (70 mph). This is because while sporty noise isn't bad for most drivers on a short journey, you don't want the vehicle to drone in the cabin on a long drive.
