Akrapovic Audi S7 Sportback (C7) Evolution Line S-AU/TI/6H: Performance and Sound Redefined

The Akrapovic Audi S7 Sportback (C7) Evolution Line S-AU/TI/6H is engineered to deliver an exhilarating driving experience while preserving everyday usability. This high-grade cat-back exhaust system works in perfect harmony with Audi’s robust V8 engine, offering measurable gains in power, torque, and acoustics—all with straightforward plug-and-play installation. Retaining the stock catalytic converters, it slots seamlessly into place and needs no ECU remap, meaning you can enjoy its benefits without worrying about complex engine tuning or emissions compliance.

How the Akrapovic Audi S7 Sportback (C7) Evolution Line S-AU/TI/6H Improves Performance

By replacing factory components downstream of the catalytic converters, the Akrapovic Audi S7 Sportback (C7) Evolution Line S-AU/TI/6H cuts 7.7 kg (17.0 lb) from the original exhaust’s 34.5 kg (76.1 lb)—reducing overall weight by 22.3%. This leaner profile translates into more responsive handling, as it lessens the load on the vehicle’s rear. Moreover, on Akrapovič’s in-house dyno, the system posts an increase of:

• +3.4 kW (4.6 HP / 4.5 HPi) at 4,500 rpm
• +7.8 Nm of torque at 4,000 rpm

These numbers underscore the exhaust’s effectiveness at unleashing the V8’s potential. Everyday driving benefits from a more substantial midrange pull and sharper throttle response, while spirited blasts along backroads feel even more dynamic.

Deep, Characterful Sound at Every Rev Range

Central to the Akrapovic Audi S7 Sportback (C7) Evolution Line S-AU/TI/6H is its ability to elevate the engine note of the Audi S7 Sportback. At low revs, it delivers a deep, resonant tone that immediately sets this model apart from the standard exhaust. As you climb the rpm band, the sound evolves into a more spirited roar—showcasing the raw character of Audi’s high-performance V8 powerplant.

Engineers at Akrapovič have integrated valves into the exhaust, managed by electric actuators that interface with the car’s driving mode electronics. Depending on your chosen program—be it Comfort, Dynamic, or any individualized setting—the valve position shifts, refining the exhaust note to suit your mood. From daily commuting to track-oriented fun, you’ll find a sound profile that matches the occasion.

Cat-Back Configuration and No ECU Remapping

Because the Akrapovic Audi S7 Sportback (C7) Evolution Line S-AU/TI/6H is a cat-back exhaust, it begins where the factory downpipes and catalytic converters end. This design choice yields key benefits:

1. No Need to Remap the ECU: With the stock catalytic converters intact, the engine control unit senses normal backpressure, maintaining the factory emissions settings.
2. Straightforward Installation: Akrapovič supplies easy-to-follow guidelines, and a professional workshop (or experienced DIY enthusiast) can generally complete the install in 120 minutes.
3. Plug-and-Play Convenience: The integrated valves work seamlessly with the vehicle’s existing electronic systems, letting you switch exhaust sound modes at the push of a button.

Styled and Designed for Visual Impact

Not only does the Akrapovic Audi S7 Sportback (C7) Evolution Line S-AU/TI/6H improve performance, it also enhances the car’s exterior appeal. With four striking, round carbon-fibre tailpipes, the system projects an aggressive stance from the rear—clear evidence of the S7 Sportback’s underlying performance pedigree. The tailpipes are carefully crafted to endure high temperatures and resist wear, while displaying a motorsport-inspired look.

The cat-back assembly itself features premium-grade titanium or stainless steel (in specified sections), which reduces weight, improves durability under high-heat conditions, and resists corrosion more effectively than conventional steel. The result is an exhaust that looks just as confident as it sounds, signaling to onlookers that this Audi S7 Sportback is far more than a stock setup.

Integrating with Audi’s Driving Programs

Audi’s sophisticated drive-mode selector allows you to tailor throttle response, steering weight, and suspension settings to personal preference. The Akrapovic Audi S7 Sportback (C7) Evolution Line S-AU/TI/6H aligns with these programs via its electronically controlled exhaust valves. Shift to Dynamic mode, and the exhaust valves open earlier or more fully, releasing a rousing V8 bellow. Roll back to Comfort mode, and the valves stay more subdued, ensuring minimal cabin noise for urban commutes or highway cruises.

This synergy between the exhaust valves and Audi’s Drive Select program means that your S7 Sportback remains equally adept at relaxed long-distance journeys and exhilarating weekend sprints—an impressive duality that sets the S range apart.
