Modern BMW performance models already give drivers some control over exhaust sound through factory driving modes. But for enthusiasts who want more control over when the exhaust valves open and close, the factory system can leave little room for customization.

The 3D Design Dual Exhaust Valve Controller provides a direct solution for select BMW models equipped with the S58 and N63 engines.

Rather than relying on ECU software changes or modifying the factory exhaust system, the controller interfaces directly with the OEM exhaust valve wiring harness. This gives the driver on-demand control over the factory exhaust valves, making it possible to change the vehicle's exhaust character according to the driving situation.

Direct Control Over the Factory Exhaust Valves

The 3D Design controller is designed around a simple concept: give the driver direct control over the exhaust valves.

The factory system automatically determines valve behavior based on driving mode and operating conditions. With the 3D Design controller installed, the driver can manually toggle the exhaust valves between their open and closed positions.

That creates a wider range of control than relying exclusively on the factory Comfort and Sport settings.

Keep the valves closed for a more subdued exhaust character during everyday driving, highway cruising, or situations where a quieter exhaust note is preferred.

Open the valves when you want a more pronounced and aggressive exhaust sound.

Dual-Channel Valve Control

Unlike a basic valve controller that treats the exhaust system as a single circuit, this 3D Design unit uses a dual-channel configuration.

The controller allows independent adjustment of the left and right exhaust valve positions, providing more precise control over the factory active exhaust system.

This makes the system particularly suited to BMW models equipped with dual factory exhaust valve circuits.

The result is a compact interface that gives the driver substantially more control over the exhaust system without replacing the factory valves themselves.

Designed to Work With the OEM Wiring

Installation is designed around the vehicle's existing exhaust valve system.

The controller installs inline with the OEM exhaust valve wiring harness, allowing it to communicate directly with the factory valve circuits without requiring permanent modifications to the vehicle's electrical system.

This approach preserves the factory exhaust valve hardware and wiring while adding an additional layer of driver control.

It also means the upgrade does not depend on changing the vehicle's ECU calibration.

No ECU Tune Required

The 3D Design Dual Exhaust Valve Controller operates independently of the engine's software calibration.

There is no need to flash the ECU or alter the vehicle's existing engine tune simply to gain manual exhaust valve control.

That makes it a useful option for enthusiasts who want to change exhaust behavior without introducing an additional software modification into an otherwise stock or tuned BMW.

The controller works with the vehicle's OEM exhaust valve wiring system, allowing the exhaust system itself to remain fundamentally unchanged.

Change the Exhaust Character When You Want

One of the biggest advantages of manual exhaust valve control is being able to choose the exhaust character based on the situation.

During normal commuting, keeping the valves closed can provide a more restrained exhaust note.

On an open road, the valves can be opened to make the exhaust sound more aggressive.

For spirited driving or track-focused use, having direct control means the driver does not have to rely entirely on the vehicle's programmed exhaust behavior.

It is a relatively small modification, but one that can make a noticeable difference in how the car feels and sounds from behind the wheel.

Designed for BMW S58 and N63 Platforms

The 3D Design Dual Exhaust Valve Controller is specifically designed for BMW applications equipped with the S58 and N63 engine platforms.

Supported S58 applications include:

• BMW G87 M2
• BMW G80 M3
• BMW G81 M3
• BMW G82 M4
• BMW G83 M4

The controller also supports the:

• BMW G16 M850i Gran Coupé with N63 engine

This vehicle-specific design allows the controller to integrate with the corresponding factory exhaust valve system rather than relying on a universal solution.

A Useful Upgrade for Modified and Stock BMWs

The controller does not require an aftermarket exhaust to be useful.

On a factory exhaust system, it can provide greater control over the sound generated by the OEM valves.

It can also complement an aftermarket exhaust system that retains compatible factory-style valve control.

That makes the 3D Design controller suitable for different stages of a BMW build. An owner can install it on an otherwise stock vehicle or incorporate it into a larger exhaust upgrade without making ECU tuning a requirement.

Japanese Engineering From 3D Design

The controller comes from 3D Design Japan, a manufacturer known for developing performance components specifically for BMW applications.

3D Design combines motorsport influence with street-oriented functionality, developing products intended to work with the vehicle rather than compromise its everyday usability.

The Dual Exhaust Valve Controller follows that same philosophy: a compact, purpose-built component that adds functionality while retaining the factory exhaust valve system.

Installation and Compatibility

Before ordering, the vehicle should be confirmed to have the appropriate factory active exhaust valve system and one of the supported S58 or N63 applications.

Because the controller is designed around the OEM exhaust valve wiring, compatibility should be verified against the exact vehicle configuration.

The unit is designed to work with the factory Comfort and Sport exhaust valve wiring systems and does not require permanent electrical modifications.
