Precision Carbon Aerodynamics for the Audi RS3 8Y Sportback and Sedan

The Akrapovic DI-AU/CA/2/G Rear Carbon Fiber Diffuser brings motorsport-grade aerodynamic refinement to the 2022-2025 Audi RS3 8Y platform in a high gloss pre-preg carbon fiber panel that replaces the factory bumper insert with zero-modification bolt-on installation. Akrapovic engineered DI-AU/CA/2/G to complement the aggressive geometry of the 8Y RS3 rear apron, enhancing underbody airflow management for improved rear stability at elevated speeds while delivering a visual transformation from performance-focused to full competition aesthetic. The autoclave-cured carbon layup maintains dimensional precision across temperature cycles, ensuring the diffuser retains its shape and finish season after season.

Key Features

  • Autoclave-Cured Pre-Preg Carbon Fiber – Same layup process used in motorsport applications; stronger and lighter than hand-laid wet-weave carbon alternatives
  • High Gloss UV-Protected Clear Coat – Multi-layer finish highlights the visible carbon weave and resists UV-induced yellowing and surface degradation
  • Sportback and Sedan Compatibility – Single part number DI-AU/CA/2/G fits both RS3 8Y body styles for 2022-2025 model years
  • Direct Bolt-On Fitment – Uses factory RS3 8Y rear bumper mounting points; no drilling, trimming, or permanent modification required
  • Aerodynamic Refinement – Designed to work with the 8Y platform's bumper geometry to manage rear airflow and reduce turbulence
  • Prop 65 Compliant Labeling – Includes required California chemical disclosure
  • Handcrafted in Slovenia – Produced at Akrapovic headquarters to motorsport quality tolerances

Frequently Asked Questions

Does DI-AU/CA/2/G fit both the Audi RS3 8Y Sportback and Sedan?

Yes. The Akrapovic DI-AU/CA/2/G is designed to fit both the RS3 8Y Sportback and Sedan body styles for 2022 through 2025 model years.

Is the DI-AU/CA/2/G a direct bolt-on or does it require modification?

The DI-AU/CA/2/G is a direct bolt-on replacement using all factory mounting points. No drilling, trimming, or permanent modification to the bumper is required.

What carbon fiber process does Akrapovic use for the DI-AU/CA/2/G?

Akrapovic uses an autoclave-cured pre-preg process, which is the same method used in motorsport applications. This produces a stronger, lighter, and more dimensionally consistent part compared to standard hand-laid carbon.

Will the high gloss finish yellow over time?

Akrapovic applies a UV-resistant clear coat over the carbon weave to prevent yellowing and fading under normal outdoor and sun exposure. Periodic waxing helps preserve the gloss long-term.

Does Akrapovic make a matte finish version of this diffuser?

Check current Akrapovic product listings for the RS3 8Y to see if a matte variant is available. The DI-AU/CA/2/G is the high gloss version.

Does this diffuser affect exhaust tip alignment on the RS3 8Y?

No. The DI-AU/CA/2/G is engineered to maintain full clearance with the RS3 8Y quad exhaust tip configuration, whether stock or with an Akrapovic performance exhaust installed.

How is the Akrapovic DI-AU/CA/2/G installed?

The DI-AU/CA/2/G uses the factory rear bumper mounting clips and bolts. Most installations can be completed in 1 to 2 hours. Professional installation is recommended to ensure correct panel gap alignment and to avoid scratching the carbon surface during handling.

Is there a warranty on the Akrapovic DI-AU/CA/2/G diffuser?

Yes. Akrapovic covers the DI-AU/CA/2/G with a 2-year warranty against manufacturing defects when purchased through an authorized Akrapovic dealer.

Does the DI-AU/CA/2/G fit the Audi RS3 8Y with the standard or Panther Black bumper?

Verify compatibility with your specific RS3 8Y bumper configuration before ordering, as regional and trim-level bumper variations may affect fitment. Contact us with your VIN for confirmation.
