Exhaust Audi A7 1 (I) (2010-2018)

The Audi A7 I offers several exhaust system types ranging from custom race catalytic converter systems, valve-equipped cat-back lines, to complete exhaust system replacements. Key options include stainless steel cat-back exhausts with valve controls for sound variation, black or chrome tips for styling, and mufflers designed for specific V6 or V8 engines. These systems improve sound quality, vehicle performance, and comply with EU emission standards.

Exhaust systems are primarily designed for the Audi A7 Quattro and V6 (3.0 TFSI/TDI) engines. Compatibility depends on the specific model year and car phase, especially distinguishing phase 1 (2010-2014) and later restyled models after 2014. Always check product details to ensure correct fitment for your vehicle's engine type and model year.

Audi A7 exhaust components are mainly made from stainless steel (Inox) ensuring durability and corrosion resistance. They often feature black, chrome, or blue exhaust tips for enhanced aesthetics. Valve technology is used in some systems to allow sound modulation between sport and daily driving modes. High-quality catalytic converters and oxygen sensors ensure compliance with emission regulations and optimal engine performance.

• Stainless steel construction for longevity
• Variable sound valves for adjustable exhaust notes
• Compliance with EU emission standards (including catalytic converters)
• Options for cat-back systems or complete replacement pipes

These materials and features contribute to improved exhaust flow, sound quality, and vehicle appearance.

Upgrading to aftermarket exhaust systems may increase engine power by improving exhaust gas flow. Typical gains estimated are between 10-20 horsepower for V6 engines due to reduced backpressure and more efficient catalytic converter operation. Additionally, sound quality is enhanced with more aggressive and deeper exhaust notes, while maintaining legal conformity to emission standards.

• Improved exhaust gas flow
• Possible horsepower gains up to 20 hp depending on model
• Enhanced exhaust sound signature
• Legal compliance with emission norms

For optimal results, professional installation is recommended.

When purchasing, ensure material quality (stainless steel preferred), compatibility with your engine model and vehicle year, and choose a product offering legal compliance (EU 70/157 standards). Consider systems equipped with valves for sound adjustment if you desire flexibility between daily driving and sporty sound levels. Also, check shipping options and warranty conditions before purchase.

• Compatibility with model year and engine type
• Material quality (high-grade stainless steel)
• Legal and emission conformity (catalytic converters included)
• Warranty and return policies
• Shipping options and delivery times

Professional installation is strongly advised for safety and performance.

These components contribute to reduced emissions and maintain engine efficiency while ensuring vehicle compliance with legal standards.

When buying or installing an exhaust system, ensure that it includes compliant catalytic converters and meets EU emission standards (such as the 70/157 regulation). Avoid removing or replacing emissions control components like catalytic converters with non-road-legal parts. Failure to comply can result in fines and vehicle inspection failures. Due to past Diesel emission issues, careful selection of exhaust systems maintaining the original post-treatment technology is strongly advised.

• Use certified catalytic converters with E24 approval
• Maintain emissions control systems as per EU regulations
• Avoid non-homologated race catalytic converters for street use
• Consult professional fitters to ensure compliance

Always verify with local regulations and ensure components match your Audi A7's engine and model year requirements.
