Take your Audi S4 or S5 to the next level with the GCA Performance Valved Sport Exhaust System. Designed specifically for 2009–2017 Audi S4 and S5 models equipped with the legendary 3.0L Supercharged V6 engine, this premium cat-back exhaust system delivers an aggressive exhaust note, improved exhaust flow, and a more engaging driving experience.
Engineered for the B8 and B8.5 platforms, this system replaces the restrictive factory exhaust with a performance-focused solution that reduces backpressure and allows the engine to breathe more efficiently. The result is improved throttle response, enhanced driving dynamics, and a deeper exhaust tone that perfectly complements the supercharged V6 powerplant.
Manufactured from premium T304 stainless steel or ultra-lightweight 6AL-4V Grade 5 titanium, the exhaust system offers exceptional durability, corrosion resistance, and long-term reliability while reducing overall vehicle weight.
The integrated electronic valve system gives drivers complete control over exhaust sound. Keep the valves closed for a refined and comfortable ride during daily driving, or open them to unleash a louder, more aggressive exhaust note whenever performance is the priority.
Featuring precision TIG-welded construction and a direct bolt-on design, this exhaust system provides excellent fitment and hassle-free installation while maintaining the ability to return the vehicle to stock at any time.
