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

Product Description

Transform the plain rear profile of your 2017‑2019 Audi A3 8V.5 facelift with the standard (Non S‑Line / SE) bumper using this S3‑style large dual exhaust rear diffuser. Designed exclusively for the standard bumper, this complete conversion kit replaces your factory rear valance with the aggressive, sporty look of the S3/RS3 — featuring a gloss black UV‑stabilized ABS polymer construction, an aggressive honeycomb design, and oversized dual‑outlet exhaust openings that dramatically enhance the visual impact of your rear end.

Finding an aftermarket diffuser for a Non S‑Line B8.5 A3 has historically been a challenge. Options for standard bumpers are extremely rare, with most aftermarket diffusers designed only for S‑Line/sport bumpers. This diffuser bridges that gap and gives your standard‑bumper A3 the aggressive dual‑exhaust look without requiring an expensive S‑Line bumper swap.

Critical Fitment Note (Read Carefully): This diffuser is designed exclusively for Audi A3 8V.5 facelift (2017‑2019) NON S‑LINE (standard / SE) rear bumpers ONLY. It will NOT fit S‑Line, S3, or pre‑facelift 8V (2012‑2016) 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.

Important – Exhaust System & Large Tips

The included large‑diameter tailpipe tips feature a dual‑outlet design to fit the factory and most aftermarket exhaust systems, designed to accept exhaust tips up to 4" in diameter.

However, this diffuser is intended for vehicles with a dual‑exhaust (two pipes – left and right) setup. If your A3 currently has a single‑side exhaust (one outlet on the left only), you will need to modify your exhaust system (install a dual‑side aftermarket cat‑back exhaust or have a shop fabricate a custom left‑right piping solution) for the large dual tips to sit correctly in the diffuser outlets. Always consult a professional exhaust shop before ordering if you are unsure.

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

Aerodynamic Benefits: The sculpted honeycomb design helps smooth airflow, reduces drag, and improves high‑speed stability — a subtle but real performance benefit that many owners notice after installation.

5 Key Features

1. Aggressive S3 / RS3 Style Design – Exclusively for Non S‑Line Bumpers
Give your standard‑bumper A3 8V.5 the sharp, race‑inspired look of the S3/RS3. The aggressive dual‑outlet honeycomb design and oversized openings create a bold, OEM+ appearance that dramatically enhances the rear profile. The large‑diameter openings are specifically designed to accommodate large 4" round tips or RS3‑style ovals (100x75mm), creating a truly menacing rear profile. The diffuser is crafted of UV‑stabilized ABS polymer to achieve its deep high‑gloss shine and provides an aggressive and sporty style that's sure to set your vehicle apart from the rest.

2. Complete Kit with Large Dual Tailpipe Exhaust Tips
All‑in‑one conversion kit includes the rear diffuser and large‑diameter exhaust tips (polished stainless steel or black chrome). Features a dual‑outlet design (left + right) that fits factory and most aftermarket exhaust systems and is designed to accept large exhaust tips up to 4" in diameter. Choose between polished stainless steel or black‑chrome finishes to match your personal style. Some RS3‑style variants also include an LED brake light for enhanced safety and a racing aesthetic.

3. Premium Gloss Black UV‑Stabilized ABS Construction (TÜV Certified)
Manufactured from high‑quality UV‑stabilized ABS polymer — the same material used in OEM bumpers and body parts. The deep high‑gloss black finish is UV‑protected to prevent fading, yellowing, or bubbling from harsh sunlight. No painting required — ready to install out of the box, or it can be repainted to match your vehicle if a custom color is desired. This product has been TUV MATERIALGUTACHTEN certified, verifying material quality and safety for road use. A premium pre‑preg dry carbon fiber version is also available for those seeking ultimate weight savings and a high‑end aesthetic. The diffuser is crafted from a UV‑stabilized ABS polymer to achieve its deep high‑gloss shine.

4. Direct Fitment for 8V.5 Non S‑Line (2017‑2019) – No Drilling Required to Bumper
Engineered for a perfect OEM+ fit onto Audi A3 8V.5 facelift NON S‑LINE (standard) rear bumpers using factory mounting locations. Installs with no drilling, cutting, or modification of any kind required to the bumper. Simply remove your currently installed valance, line up all tabs, and lightly press the diffuser in place until the tabs click into position. Self‑tapping screws are provided for additional security. The product will arrive with a protective film — do not remove the protective film until you are certain the product fits, as removal will void the return policy.

5. CE & TUV MATERIALGUTACHTEN Certified + EPR Compliant
This diffuser is CE certified, meeting European safety and quality standards for automotive aftermarket parts. It has also received TUV MATERIALGUTACHTEN certification, verifying material quality and safety for road use. The product also complies with EPR (France/Germany) environmental regulations for packaging and waste management. The holographic verification sticker confirms authenticity — removal of the sticker will void returns, so only remove once you are certain the product fits.

Frequently Asked Questions

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

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

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, you have the standard (Non S‑Line / SE) bumper.

Q3: Does the kit include large exhaust tips?

A: Yes! The complete kit includes large‑diameter dual tailpipe exhaust tips (polished stainless steel or black chrome), 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 to the bumper 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.
