Why upgrade your S3 with this GPF-back system

• Immediate sound upgrade for GPF cars while keeping the filter in place
• 3 inch, 76.2 mm mandrel bent pipework for improved flow and performance potential
• Choice of sound level: resonated for a refined, sporty note or non resonated for a louder, more aggressive character
• Quad 88.9 mm tailpipes angled to suit the S3 rear bumper, available in polished stainless or stealthy matt black
• Substantial weight saving versus the factory rear section, enhancing agility
• Hand built in Sheffield, UK, from corrosion resistant grade 304 stainless steel
• Lifetime guarantee from the manufacturer on the exhaust for peace of mind
• Supplied with required gaskets and fittings for a straightforward bolt-on installation

Sound options to suit your drive

Resonated includes a centre silencer for a tasteful, deeper tone that is perfect for daily use and motorway cruising. Non resonated removes the centre box for a louder, sportier soundtrack with more presence on throttle. Both versions keep the GPF in place.

Fixed valve design explained

This system removes the OE exhaust valve functionality. Changing Audi Drive Select modes will not alter the exhaust volume. Running a non valved rear section does not harm the vehicle. Cobra Sport has tuned the system so you get a well judged sound profile without the need for flaps.

Engineered for the 2.0 TFSI

Cobra Sport’s R&D team balanced tone, flow and aesthetics specifically for the S3 8V facelift. The freer flowing rear section reduces restriction after the particulate filter and complements other breathing upgrades. The big gain you will feel day to day is the sharper throttle response and the more characterful note that suits the S3’s sporting nature.

Tailpipe choices

• Quad 88.9 mm angled tips
• Finish options: highly polished stainless or durable matt black

Materials and build

• Full T304 stainless steel construction
• Expert TIG welded joints
• Lightweight design compared to stock rear section

Real world feedback

We run these on customer cars and our own builds. Fitment is spot on, the tips sit beautifully in the diffuser, and the sound is exactly what S3 owners ask for. The resonated option keeps things civil for daily driving while the non resonated version turns the excitement up without being boomy when cruising.
