Iconic Performance Engineering of the Audi B7 RS4

The Audi B7 RS4, made between 2006 and 2008, is a hallmark of German engineering in the compact luxury car scene. Its powerful 4.2 litre V8 engine produces 414 horsepower and 317 lb ft of torque, paired with a six speed manual gearbox and Audi’s renowned quattro all wheel drive system. Capable of accelerating from 0 to 60 mph in just 4.6 seconds, the B7 RS4 delivers an engaging and responsive driving experience, made even more exciting with an upgraded Audi Rs4 Exhaust System.

DKU Performance Enhancements for Ultimate Driving

This particular RS4 was already equipped with Milltek decats, improving exhaust flow by removing restrictive catalytic converters. To build on this setup, we completed a full straight pipe conversion, creating a freer flowing Audi Rs4 Exhaust that maximises gas flow and enhances the natural V8 tone. The system was finished with upgraded RS style exhaust tips, giving the rear of the car a sharper and more purposeful appearance.

Balanced Design and Competitive Edge

With a length of 4590 mm, a wheelbase of 2650 mm and a kerb weight of 1650 kg, the B7 RS4 offers excellent balance and road presence. Competing with models such as the BMW M3 and Mercedes C63 AMG, it stands out for its naturally aspirated V8 character and precise handling. Paired with a performance focused Audi Rs4 Exhaust upgrade, the engine breathes more efficiently and delivers a far more engaging driving experience.

With the addition of a custom straight piped setup to complement the existing Milltek decats, we reduced exhaust back pressure and significantly improved throttle response. The upgraded Audi Rs4 Exhaust System delivers a louder, deeper and more aggressive V8 soundtrack while maintaining everyday usability and the confidence of quattro traction.
