Transform the sound and performance of your 2017-2023 BMW 640i GT or 640i xDrive GT with the GCA Performance Valved Sport Exhaust System. Designed specifically for the G32 Gran Turismo equipped with the 3.0L B58 turbocharged inline-six, this premium cat-back exhaust delivers a deeper exhaust note, increased airflow, and improved driving dynamics.
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 over the factory exhaust.
The integrated electronic valved system allows you to control your exhaust sound at the touch of a button. Keep the valves closed for a refined factory-like driving experience, or open them to unleash a more aggressive exhaust tone while reducing backpressure for improved performance.
Precision mandrel-bent tubing and TIG-welded construction maximize exhaust flow, helping improve horsepower, torque, throttle response, and turbo efficiency while maintaining OEM-quality fitment.
