Transform the sound, performance, and driving experience of your 2025+ BMW X3 M50 with the GCA Performance Valved Sport Exhaust System. Designed exclusively for the G45 and G48 platforms equipped with the 3.0L Turbo B58 inline-six, this premium cat-back exhaust delivers increased airflow, improved throttle response, and a deep performance exhaust note while maintaining everyday comfort.
Developed under the GCA Performance line, this exhaust system is available in high-quality T304 stainless steel or Grade 5 (6AL-4V) titanium, providing exceptional durability, corrosion resistance, and significant weight savings compared to the factory exhaust system.
The electronically controlled valve system allows you to choose your driving experience with the push of a button. Keep the valves closed for refined daily driving or open them to unleash a more aggressive exhaust note and maximize exhaust flow. Larger mandrel-bent tubing and precision TIG-welded construction reduce backpressure, helping the turbocharged B58 engine breathe more efficiently for improved horsepower, torque, and turbo response.
Whether you're building the ultimate daily driver or a performance-focused SUV, this exhaust system delivers the perfect combination of sound, quality, and performance.
