What causes the distinctive exhaust note of the Audi R8?

I have recently noticed the unique sound of the Audi R8's exhaust and am curious what specific elements or components contribute to this signature sound. I have heard it described as a combination of growls, snarls, and pops. Can someone explain the science behind this and how it differs from other high-performance supercars?

The Audi R8's exhaust note is a result of its naturally aspirated V10 engine combined with a performance exhaust system that features variable exhaust flaps. These flaps open and close based on engine speed, load, and drive mode, allowing for a deeper and more aggressive sound at higher RPMs.

If you want to enhance the exhaust note of your own Audi R8, consider upgrading to an aftermarket exhaust system. These can offer even more customization and control over the sound, and some even offer bypass valves to completely open the exhaust for maximum volume.

Unlike many other high-performance cars which use turbochargers, the Audi R8's naturally aspirated engine allows for more low-end torque and a more immediate response. This also contributes to the unique sound of the exhaust, as there is no muffled turbo sound.
