Description
For an enthusiast-spec 2021+ Audi RS 3 (8Y) Sportback / Sedan, this Rear Carbon Fiber Diffuser finishes the rear bumper area around the exhaust outlets with an application-specific carbon component. The difference is integration: the rear treatment is meant to look resolved with the compatible exhaust, not simply added beneath the bumper.
The important distinction on 2021+ Audi RS 3 (8Y) Sportback / Sedan is that this is not a universal substitute: it is the cataloged Akrapovič part for this application under SKU AKRDI-AU/CA/2/G.

Because this is an Audi Sport-oriented application, the finished installation deserves the same attention as the individual part—surrounding hardware, fitment, and visual integration all matter. Carbon fiber is part of the specified product, so its appearance is integral to the component rather than added as unrelated trim.
Akrapovič built its reputation through high-end exhaust engineering and motorsport, and its road-car catalog carries that same emphasis on materials, fitment, and vehicle-specific design. It makes the most sense for Audi enthusiasts who prefer understated, premium engineering over a generic aftermarket look, particularly on builds where the quality of the hardware matters as much as the fact that the car is modified.
