Transform the sound, performance, and driving experience of your 2018-2025 Audi RS4 or Audi RS5 with the GCA Performance Valved Sport Exhaust System. Specifically engineered for B9 and B9.5 models equipped with the 2.9L Twin-Turbocharged V6 engine, this premium cat-back exhaust system delivers an aggressive exhaust note, improved exhaust flow, and enhanced driving engagement.
Designed to replace the restrictive factory exhaust system, this performance exhaust reduces back pressure and promotes more efficient exhaust gas evacuation, allowing the engine to breathe more freely. The result is improved throttle response, enhanced performance potential, and a more exhilarating driving experience throughout the RPM range.
A key feature of this system is its electronically controlled valved design. With the valves closed, the exhaust remains refined and comfortable for daily driving. Open the valves, however, and the RS4 or RS5 unleashes a deeper, more aggressive exhaust tone that fully complements the character of Audi’s twin-turbo V6 engine.
Available in either premium T304 stainless steel or ultra-lightweight Grade 5 Titanium (Ti-6Al-4V), this exhaust system offers exceptional durability, corrosion resistance, and heat tolerance. Precision TIG-welded construction ensures maximum strength, long-term reliability, and precise fitment.
The complete cat-back system includes both the mid-pipe and axle-back sections, along with RS-style exhaust tips for a clean, performance-inspired finish. Designed as a direct-fit upgrade, the system installs using factory mounting locations and remains fully reversible.
