Unlock the true sound and performance of your Audi S3 with the GCA Performance Valved Sport Exhaust System. Designed specifically for 2014–2020 Audi S3 models, this premium cat-back exhaust system delivers a more aggressive exhaust note, improved exhaust flow, and enhanced driving enjoyment while maintaining the flexibility of a refined daily driver.
Engineered in-house under the GCA Performance line, this exhaust system is available in either premium T304 stainless steel or ultra-lightweight 6AL-4V Grade 5 titanium construction. Both materials offer exceptional durability, corrosion resistance, and long-term reliability while helping reduce overall exhaust system weight.
Designed to maximize the performance potential of the Audi's turbocharged 2.0L engine, the system reduces exhaust backpressure and improves flow, allowing the engine to breathe more efficiently. The result is sharper throttle response, a more engaging driving experience, and a deeper, sportier exhaust tone.
The integrated electronic valve system allows you to adjust the exhaust sound instantly. Keep the valves closed for a comfortable and refined driving experience or open them to unleash an aggressive exhaust note whenever performance driving calls.
This complete cat-back system includes both the mid-pipe and axle-back sections along with premium quad exhaust tips that perfectly complement the sporty styling of the Audi S3. Precision TIG-welded construction ensures exceptional fitment, durability, and long-lasting performance.
