Audi S3 (8Y) Saloon/Sedan OPF/GPF-Back Performance Exhaust | Cobra Sport 3in (76mm) Cat-Back Style Centre & Rear Section | Valved or Non-Valved Sports Back Box Upgrade

Turn up the excitement on your Audi S3 8Y saloon

Give your S3 the voice and presence it deserves with this Cobra Sport rear-section upgrade. Designed to run from the petrol particulate filter backwards (often called OPF/GPF back), it replaces the centre and rear sections with free-flowing 76.2 mm (3 inch) pipework for a deeper, more characterful soundtrack and a sharper driving feel. It looks the part, sounds the part and delivers that premium sports-car tone every time you press the start button.

We run this setup on customer cars and the feedback has been consistently excellent. If you want a quality exhaust system that enhances sound without hassle, this is the one to choose.

Why enthusiasts choose this system

• 3 inch / 76.2 mm pipework for improved flow and a richer exhaust note
• Fits from the GPF/OPF section back, replacing the middle and rear sections
• Direct replacement with all required fittings and gaskets supplied
• Developed on the track, released for the road – motorsport proven technology
• Available with valve control or in a fixed-sound, non-valved setup

Choose your sound

Valved version: Keeps the factory valve functionality. Switch between Comfort and Dynamic in Audi Drive Select and the sound changes accordingly, just as you expect, only better.

Non-valved version: Fixed, consistent tone in every drive mode. No impact on vehicle running – simply a set-and-enjoy sports sound tailored by Cobra Sport.
