Variable valve options allow switching between sport and daily driving modes.

Yes, most aftermarket exhaust systems for the Audi A7 I are designed to respect EU emission standards, especially when equipped with catalyst-compatible components and compliant catalytic converters.

• Cat-back systems maintain original catalytic converters, ensuring emission compliance
• High-quality stainless steel construction avoids degradation that might cause emission issues
