Why do some Audi A7 models have Quad Exhaust Pipes?

I've noticed that not all Audi A7 models have quad exhaust pipes, and I'm curious about the reasoning behind it. Is it just for aesthetics or is there a functional purpose?

The quad exhaust pipes you see on certain Audi A7 models are not just for aesthetic purposes. They actually allow for better engine performance by improving exhaust flow and reducing back pressure. This results in both increased power and a more aggressive engine sound.

In addition to the improved engine performance, quad exhaust pipes on Audi A7 models also serve as a visual indicator of a more powerful engine. This makes it easier for car enthusiasts to quickly identify higher performance versions of the car.

As a long time Audi A7 owner, I can say that quad exhaust pipes also add an extra touch of luxury and sportiness to the overall look and feel of the car. It definitely enhances the driving experience and makes for a great conversation starter.
