Description
Upgrade your BMW G14 G15 840i with the DCE Parts Valvetronic Cat-Back Exhaust, designed to provide an ideal balance of refined everyday drivability, highway comfort, and a more engaging exhaust sound.
Manufactured from high-grade stainless steel, with titanium available as an optional material, this valved exhaust system allows you to adjust the exhaust character according to your driving preferences. With the valves closed, the system provides a refined and comfortable exhaust note that is well suited to daily driving and long highway journeys. Opening the valves produces a sportier and more aggressive exhaust sound, particularly under acceleration.
Electronic & Vacuum Valved Exhaust System
The DCE Parts exhaust system can be configured with either electronic or vacuum valve actuators, depending on the selected setup. The exhaust valves are controlled through a dedicated controller unit, giving you convenient control over the exhaust sound.
The valve control system is designed independently from the vehicle's brake system, helping prevent unwanted changes in brake pedal feel. The high-quality valve components are engineered for reliable operation and provide the flexibility to switch between refined cruising and a more aggressive exhaust character.
High-Grade Construction
The exhaust system is manufactured from high-grade stainless steel for durability and long-term reliability. Titanium construction is also available as an optional upgrade.
Optional exhaust tips are available, allowing you to customize the appearance of the exhaust system to complement your BMW 8 Series.
