Audi S3 8V / 8V.5 Facelift (2019–2020) Sportback 5dr OPF/GPF‑Back Valved Exhaust – T304 Stainless Performance Catback Upgrade, Quad Tips, Resonated or Non‑Resonated, Drive Select Compatible

Audi S3 8V.5 OPF-back valved exhaust upgrade for 2019–2020 5 door Sportback. Transform the soundtrack and look of your S3 with a UK-made stainless system that keeps the factory valve control and turns everyday drives into something special. Perfect for owners wanting a deep, refined tone in Comfort and an aggressive note in Dynamic without drone.

Fitment note: this system is for petrol particulate filter vehicles only, also known as OPF or GPF. If your car is a non-OPF pre-facelift model, please see our other S3 listings.

Why S3 owners choose this upgrade

• Built from mandrel-bent T304 stainless steel in 76.2 mm pipework for excellent flow and durability.
• OPF-back layout replaces the mid section and rear section while retaining the factory particulate filter.
• Valve-controlled design works with Audi Drive Select, so the sound switches from subtle to sportier at the press of a button.
• Choose your sound: resonated for a more civilised tone or non-resonated for a louder, more spirited character.
• Quad 88.9 mm angled tailpipes in your choice of polished stainless or stealthy matt black for a purposeful rear end.
• Hand TIG-welded in the UK with premium materials for long-term reliability, supplied with all required clamps and fittings.
• Lifetime guarantee on the system for ultimate peace of mind.

Real-world gains you can feel and hear

This exhaust frees up the 2.0 TFSI to breathe, sharpening throttle response and adding a richer, deeper note without the boom. Compared to stock hardware, the manufacturer’s cat-back testing shows a substantial weight saving of around 30 percent on like-for-like components, dropping from 26.9 kg to 18.8 kg, helping the S3 feel more agile. The OPF-back layout here follows the same lightweight, free-flowing construction principles.

Built for the 8V facelift S3 hatchback with OPF

Designed specifically for the 2019 and 2020 5 door Sportback, this upgrade keeps the OEM valve motors and integrates seamlessly with Drive Select modes, maintaining that quiet-to-loud functionality you want in a daily-driven performance car.

Our experience and customer feedback

We run this system on our own cars and our customers love the transformation. The fit and finish are excellent, the tone is addictive, and the dual-character valve control makes it ideal for commuting and weekend blasts alike.
