Helmholtz

 You may be asking what is that small tube on our Resonator Delete? The small tube is a Helmholtz Resonator. In the exhaust system the Helmholtz will be a container of gas (usually air) with an open hole (neck or port) going into the Resonator. A volume of air/gas in and near the open hole vibrates because of the 'springiness' of the air/gas inside.

A common example is an empty bottle: the air inside vibrates when you blow across the top!

What is Drone?

Drone is a point at which the exhaust note resonates in the cabin and creates a noise which most drivers dislike, so the decibels and frequency can be slightly different depending on the driver and the car. This is why we created Anti Drone Resonator Deletes.

When removing a standard resonator this is where you pay the difference between someone who just wants to give you a pipe and throw it on a car and a company who has designed a product to do a specific job, who have taken the time to do the research, development and testing to make the product the best it can be!

Comes free with clamps and installation guide on request.

​

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