The Milltek Sport Cat Back exhaust system is designed for the Audi RS6 C7 models, powered by the powerful 4.0-liter TFSI bi-turbo engine and Quattro all-wheel drive. This exhaust solution is an excellent upgrade for the driver who wants a deeper, more open and sporty sound and better exhaust flow without compromising on drivability or comfort.

The Cat Back system replaces the rear section of the exhaust system, freeing up the flow and bringing out the engine's natural character in a stylish but unobtrusive way.

Rich and controlled V8 soundscape

Milltek has tuned this system specifically to support the RS6 C7's V8 bi-turbo engine:

• Deeper and richer sound at idle

• Stronger and more vibrant sound during acceleration

• Sporty yet refined sound even at high revs

• No annoying resonance or unpleasant drone during normal driving

The sound profile is designed to highlight the RS6's performance and engine character without compromising on everyday use.

Improved exhaust flow and response feel

Milltek Cat Back Exhaust System:

• reduces exhaust back pressure at the rear end

• improves engine throttle response sensitivity

• enhances exhaust gas flow throughout the entire rev range

• may support other performance component benefits, such as software updates

The freer-flowing structure gives the engine better breathing capacity and a more dynamic driving feel.

Direct bolt-on installation

The exhaust system is designed:

• to fit directly into the car's original mounting points

• for installation without structural changes or welding

• to retain the functionality of the original chassis and drivetrain

OEM-level fit ensures a precise fit and a high-quality finish .

304L Aircraft Grade Stainless Steel

The entire system is made of high-quality 304L grade stainless steel , which offers:

• excellent corrosion and heat resistance

• long-lasting structure even in intensive use

• flow-optimized internal design

• carefully finished TIG welds

The choice of materials meets the premium quality standards of Milltek products.
