Sport exhaust system, type Cat-back by Milltek designed for Audi S5 B9 3.0 TFSI in Coupe and Convertible versions.
Made entirely of stainless steel and fitted with 4 exhaust tips. The exhaust is available in louder Non-resonated and quieter Resonated versions. All available versions have rear mufflers with valves controlled by the vehicle electronics.
The system is compatible with the stock catalytic converter. No modifications are required for installation.
Active Valve Control – an optional module providing full control over the exhaust valves. It allows factory valve settings to be changed and customized to driver preferences.
With almost four decades of continuous research and development, the product range continues to expand to meet the high expectations of owners of brands such as Audi, Volkswagen, Porsche, Ford, BMW and Alfa Romeo.
The company draws on its motorsport heritage in series such as BTCC and the Volkswagen Racing Cup, as well as endurance racing, to create exhausts that deliver real power gains and improved sound across a wide range of vehicles.
All Milltek exhaust systems are designed, developed and handmade in the United Kingdom by highly skilled specialists. Every exhaust component is made exclusively from T304 stainless steel, providing an exceptionally long service life.
Precision pipe bending and increased pipe diameter optimize exhaust flow and maintain vehicle power without sacrificing mid-range torque. All Milltek exhaust systems undergo detailed acoustic testing to provide a sporty exhaust note without drone.
Warranty
All Milltek Cat-back exhaust systems carry a lifetime warranty against corrosion and manufacturing defects. Sport catalytic converters and downpipes are covered for 2 years or 80,000 km. The warranty applies only to the original owner of the exhaust system.
Sound versions
Most Cat-back exhaust systems are available in two sound versions: Non-resonated and Resonated. The former is louder and provides a sportier sound, while remaining intended for public-road use and comfortable enough for daily driving. Quieter Resonated versions are intended for customers who want to improve vehicle performance while keeping the engine sound as close to stock as possible.
Installation
All Milltek products are designed to fit the specific vehicle model perfectly. Most exhaust systems are installed on a Plug&Play basis. Every product includes the necessary installation accessories, such as clamps and reducers. A Cat-back exhaust always includes the correct adapter to connect to the stock exhaust.
