Description
Upgrade the sound, appearance, and driving experience of your BMW B58-powered 340i or 440i with the DCE Parts Valved Cat-Back Exhaust. Designed specifically for the BMW F30/F31 340i and F32/F36 440i, this exhaust system is constructed from high-grade stainless steel and engineered to provide a refined driving experience with the flexibility to switch between a comfortable, subdued exhaust note and a more aggressive sound.
The integrated electronic valve system gives you control over the exhaust character at the touch of a button. With the valves closed, the system is designed to maintain a comfortable and civilized driving experience, making it well suited for daily driving and highway journeys. Cabin noise remains close to the original exhaust character, helping preserve long-distance comfort.
Open the valves when you want a more pronounced and sporty exhaust note. The system delivers a deeper, more aggressive sound under acceleration while maintaining a surprisingly comfortable level of refinement during normal driving. This combination provides the flexibility of a quiet exhaust for everyday use and an enhanced exhaust note when you want a more engaging driving experience.
Electronic Valved Exhaust System
DCE Parts uses high-quality electronic exhaust valve actuators controlled through a dedicated valve controller. The durable valve assemblies are designed to provide reliable operation and allow you to switch between the available exhaust sound modes conveniently.
The system includes the necessary electronic components and accessories for valve operation, including a remote control, valve controller, cables, and 12V power supply.
