2017-2019 For Audi A3 S3 8V.5 Non S-line rear diffuser and tailpipe

Product Description

Transform the rear profile of your 2017‑2019 Audi A3 8V.5 (facelift) Non S‑Line with this S3‑style rear diffuser complete with dual tailpipe exhaust tips. Designed exclusively for the standard (Non S‑Line) bumper, this diffuser replaces your factory rear valance with the aggressive, sporty look of the S3 — featuring a gloss black UV‑stabilized ABS polymer construction, aggressive honeycomb design, and dual‑outlet exhaust openings that dramatically enhance the visual impact of your rear end.

The 8V.5 facelift brought LED headlights, sharper lines, and updated bumpers to the A3 lineup, but the factory rear diffuser on Non S‑Line models remains noticeably plain. This S3‑inspired rear diffuser solves that problem without requiring an expensive S‑Line bumper swap. The honeycomb lower section transforms the rear, and the included dual exhaust tips give your A3 a true performance‑oriented look that complements both factory and aftermarket exhaust systems.

⚠️ Critical Fitment Note (Read Carefully): This diffuser is exclusively for Audi A3 8V.5 facelift (2017‑2019) NON S‑LINE (standard) bumpers ONLY. It will not fit S‑Line or S3 models. We offer two versions: one for Sedan (Saloon) and one for Sportback (Hatchback). Choose the correct one for your body style. If you have an S‑Line or S3 model, please check our other listings. Additionally, if your vehicle is equipped with a factory trailer hitch, this diffuser will not be compatible.

📌 Complete 1‑Stop Conversion Kit: Includes rear diffuser + dual exhaust tips + self‑tapping screws + 3M VHB tape + installation manual.

Aerodynamic Benefits: The honeycomb lower section helps smooth airflow, reducing drag and improving high‑speed stability.

Frequently Asked Questions

Q1: Will this fit my 2017‑2019 Audi A3 8V.5 Non S‑Line?

A: Yes, if your vehicle is a 8V.5 facelift (2017‑2019) with the standard (Non S‑Line) rear bumper. This diffuser will NOT fit S‑Line or S3 models. Contact us with your VIN for confirmation.

Q2: How do I know if my A3 has S‑Line or Non S‑Line?

A: The S‑Line exterior package includes sportier front/rear bumpers, side skirts, and S‑Line badging on the front wings. If your A3 has a smooth, non‑aggressive rear bumper without the recessed diffuser area, you have the standard (Non S‑Line) bumper.

Q3: Does this kit include exhaust tips?

A: Yes! The complete kit includes dual tailpipe exhaust tips, self‑tapping screws, and 3M VHB tape — a complete 1‑stop solution for your rear‑end transformation.

Q4: Does the diffuser require painting?

A: No. It comes in a premium high‑gloss black UV‑stabilized finish — ready to install out of the box. UV‑protection prevents fading and yellowing. If you decide to paint it, primer must be used first.

Q5: Is drilling required for installation?

A: No drilling, cutting, or modification of any kind is required when using factory mounting locations. However, self‑tapping screws are recommended in corners and tabs for best fitment. The product requires the removal of the original diffuser; self‑tapping screws are needed to secure fitment of the new diffuser.

Q6: Is professional installation required?

A: Yes, strongly recommended. Professional installation by someone with aftermarket product experience is highly advised. The rear bumper must be removed to install this diffuser properly.
