Audi S3 (8V Facelift) (19-20) (GPF Models) Saloon (Valved) GPF Back Performance Exhaust

Fitment note: For 2019–2020 Audi S3 8V facelift models equipped with a petrol particulate filter (GPF/OPF) only. For non-GPF cars, please see our main 8V S3 listings.

Transform your Audi S3 8V.5 saloon’s soundtrack and road presence with this premium valve-controlled rear system from Cobra Sport. Built for GPF/OPF cars, this OPF-back setup replaces the centre and rear sections with free-flowing 3 inch (76.2 mm) pipework, unlocking a deeper, sportier tone while keeping day-to-day refinement intact.

We’ve fitted this on customer S3s and the feedback has been fantastic: sharper throttle response, a richer exhaust note and OEM+ integration thanks to the retained factory valve control. Choose your sound level with resonated or non-resonated configurations to suit your daily drive or weekend blasts.

Why choose this S3 OPF-back upgrade

• Designed for 8V facelift S3 saloon (2019–2020) with OPF/GPF
• Valve-operated flaps retained for full Drive Select functionality (Comfort to Dynamic)
• 3 inch / 76.2 mm mandrel-bent tubing for improved flow and tone
• Resonated setup for subtle refinement, or non-resonated for a louder, more aggressive note
• Supplied with all required gaskets and hardware for a straightforward install
• Hand-crafted from T304 stainless steel, TIG-welded in Sheffield
• Lifetime guarantee on the exhaust system for ultimate peace of mind

Tailpipe options

Signature quad exit with angled 88.9 mm tips, available in a choice of finishes: classic highly polished stainless or stealth matte black. The perfect visual match for the S3’s sporty rear bumper and diffuser.

Sound options to suit your driving

• Resonated: includes centre silencer for a refined, OEM+ tone with enhanced character under load.
• Non-resonated: removes the centre silencer for a louder, more spirited note and increased presence.

Cobra Sport quality and performance

Cobra Sport’s motorsport-proven engineering delivers serious results. Their development programme on the S3 platform has demonstrated meaningful gains and impressive weight savings. For reference, swapping to the Cobra Sport cat-back on the S3 achieved around a 30% reduction versus the OE system, dropping from 26.9 kg to 18.8 kg on like-for-like parts. Expect the same obsessive attention to weight, flow and durability in this OPF-back configuration.
