Helmholtz

You may be wondering what the small tube is on our Resonator Delete? 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 it. The volume of air/gas in and near the open hole 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; the decibels and frequency can vary slightly depending on the driver and the car. 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, who has taken the time to research, develop, and test to make the product the best it can be!

Comes free with clamps and installation instructions upon request.

RPM PERFORMANCE Anti Drone Resonator Deletes have been designed to reduce drone throughout the rev range of a stock system, specifically cruising speeds on motorways on UK roads (70 mph). This is because if you are in the car for a short journey, a bit of sporty noise isn't a bad thing for most drivers, but if you are travelling for a long period, you don't want the vehicle to drone in the cabin.
