The Akrapovic DI-PO/CA/3/G is a high gloss carbon fiber rear diffuser engineered for the 2016-2017 Porsche 911 Carrera S, Carrera 4, Carrera 4S, and GTS on the 991.2 platform. Built at Akrapovic's production facility in Slovenia with motorsport-grade woven carbon fiber and a UV-resistant high gloss clear coat, this DI-PO/CA/3/G diffuser is a direct-fit replacement for the OEM lower rear bumper diffuser panel on covered 991.2 variants. It brings a more aggressive rear aesthetic to the Carrera 991.2 without permanent modification, and the high gloss carbon weave delivers a premium material upgrade that stands apart from the factory plastic or painted component it replaces.

Frequently Asked Questions

Which 911 991.2 trims does the DI-PO/CA/3/G fit?

The DI-PO/CA/3/G is confirmed for the 2016-2017 Porsche 911 Carrera, Carrera S, Carrera 4, and Carrera 4S on the 991.2 platform, as well as the 2017 Carrera GTS and Carrera 4 GTS variants. These trims share the same rear bumper and diffuser mounting architecture on the 991.2 generation.

Is the DI-PO/CA/3/G a direct replacement for the OEM diffuser?

Yes. The DI-PO/CA/3/G is a direct-fit replacement for the lower rear diffuser panel on the 991.2 Porsche 911 rear bumper. It uses the existing OEM mounting points and requires no additional brackets, adapters, or cutting.

What is the difference between the 991.2 and 991.1 for this diffuser?

The 991.2 is the facelifted generation of the 991-series Porsche 911, introduced for the 2016 model year with updated aerodynamics and revised rear bumper styling. The DI-PO/CA/3/G is designed specifically for 991.2 geometry and will not be a direct fit for 991.1 bumpers without modification.

Does installation require permanent modification to the 991.2 bumper?

No. The DI-PO/CA/3/G installs using the OEM mounting points on the 991.2 rear bumper and the hardware included in the package. The installation is fully reversible.

What maintenance does the high gloss carbon require?

Hand wash with a pH-neutral shampoo and apply a carnauba or ceramic spray wax periodically to protect the high gloss clear coat. Avoid abrasive pads and solvent-based cleaners. Inspect for stone chips after track sessions and address promptly to prevent moisture working under the clear coat.

How does the DI-PO/CA/3/G compare to the OEM 991.2 rear diffuser?

The OEM Porsche 911 991.2 lower rear diffuser is a black plastic or body-color painted component depending on trim. The Akrapovic DI-PO/CA/3/G replaces it with motorsport-grade high gloss carbon fiber, offering a significant visual upgrade and minor weight reduction while maintaining factory-quality precision fitment.

Is this compatible with both coupe and cabriolet 991.2 variants?

The DI-PO/CA/3/G is a rear bumper diffuser and fitment is determined by the rear bumper architecture rather than body style. Verify compatibility with your specific 991.2 variant, as coupe and cabriolet share the same rear bumper on the 991.2 for the covered trims.

Is this a genuine Akrapovic part?

Yes. The DI-PO/CA/3/G is manufactured by Akrapovic d.d. at their facility in Slovenia and carries the official Akrapovic part number. It is not an aftermarket replica or OEM-equivalent copy.

Installation Instructions

  1. Ensure the vehicle is on a flat, stable surface with the rear bumper area fully accessible.
  2. Remove the OEM lower rear diffuser from the 991.2 bumper by releasing all retaining clips and fasteners.
  3. Clean all mounting points and the surrounding bumper surface before installing the carbon diffuser.
  4. Trial-fit the DI-PO/CA/3/G to confirm alignment with all OEM mounting holes and panel edges before securing.
  5. Install all provided fasteners and clips by hand, confirming the diffuser sits flush with the bumper on all sides.
  6. Torque all fasteners to the specification in the Akrapovic instruction sheet included in the package.
  7. Inspect all panel edges and gaps for OEM-level fitment before returning the vehicle to service.
  8. Apply a light wax coat to the carbon surface as initial protection before first drive.
