Audi RS4 B9 2.9T 2019+ High Performance Valved Titanium Exhaust System

This titanium valved exhaust system is engineered to complement the 2.9T engine in the RS4 B9 with improved flow characteristics and reduced system weight. Titanium construction provides excellent heat resistance and a more responsive driving feel. With the valves closed, the exhaust maintains a refined tone suitable for everyday use, while opening them transforms the sound into a more aggressive, performance-focused note. APEX provides this system as a direct-fit upgrade with full valve functionality and factory-compatible integration.
