APR 21-25 Audi RS6/RS7 (C8) Catback Exhaust System with Dual 3-Inch Piping and RS-Style Tips

The entire system is increased to a dual 3” (72mm) exhaust path. With the exhaust valves open, the exhaust gasses travel uninterrupted from the front of the system out through the exhaust tips. When exhaust gasses travel into the multichambered rear muffler / resonator, they continue uninterrupted and a Helmholtz resonator reduces drone frequences without restricting flow on the open-valve path. With the valves closed, exhaust gasses travel through a sound reduction path via a smaller 2.5” (63.5mm) pipe, reducing volume and allowing the system to act more civilized when needed. Finally the system terminates via oversized 8.23”x4.76” (211x21mm) RS-style oval exhaust tips. The tips feature a diamond black finish and a subtle APR logo for a refined touch. Fits Audi RS6 21-25, RS7 21-25

Upgrade your Audi RS6 or RS7 with the APR 21-25 C8 Catback Exhaust System, designed to enhance performance, sound, and style. Crafted from premium T304 stainless steel with TIG welding, this system ensures strength and durability while delivering a refined appearance. The system features a dual 3-inch (72mm) exhaust path that allows exhaust gases to flow freely when the valves are open, providing maximum performance. When the valves are closed, exhaust gases are routed through a quieter, smaller 2.5-inch (63.5mm) path, reducing volume for a more civilized driving experience. The integrated Helmholtz resonator minimizes drone frequencies without restricting airflow, resulting in a balanced sound profile.
The exhaust system includes a complete catalyst-back setup with precision brackets and slip clamps for an easy, hassle-free installation. The design incorporates smooth transitions and straight-through components that maximize exhaust flow, delivering an impressive 9 horsepower and 16 ft-lbs of torque gains to all four wheels. Valve-controlled rear mufflers dynamically adjust sound based on driving style, offering an engaging exhaust note when desired. The system terminates with oversized 8.23-inch x 4.76-inch (211 x 21mm) RS-style oval tips finished in a diamond black coating, subtly branded with the APR logo for a refined look. Fully emissions compliant, this system is suitable for street use and adheres to regulatory standards.
Designed specifically for the 2021-2025 Audi RS6 Avant and RS7 Sportback models, this exhaust upgrade strikes a perfect balance of performance, sound, and style. The mandrel-bent piping ensures a clean finish while the dual quad exits create a bold visual statement. The system's advanced engineering allows enthusiasts to enjoy a deeper, more aggressive exhaust note while maintaining everyday civility, making it an ideal upgrade for those seeking both power and refinement.
