Modern performance vehicles often feature electronically controlled exhaust valves.

These systems automatically open and close based on drive mode, engine speed, throttle position, and factory programming.

While this technology helps balance comfort and performance, many enthusiasts want greater control over when their exhaust valves remain open or closed.

SST Spezialsteuergeräte develops plug-and-play exhaust valve controllers that give drivers direct control over factory active exhaust systems while preserving straightforward installation and OEM integration.

Control the Exhaust on Your Terms

Factory programming determines how active exhaust valves behave.

In many vehicles, the valves close during normal driving, even when drivers would prefer a more aggressive exhaust note.

SST controllers allow owners to override those factory strategies, providing manual control of the exhaust valve position without permanently modifying the vehicle's original exhaust system.

Plug-and-Play Installation

One of SST's primary design goals is preserving OEM simplicity.

Most controllers connect using factory wiring connectors without requiring permanent modifications to the vehicle's electrical system. This allows installation to be completed with minimal disruption while maintaining a clean, factory-style appearance.

Preserve the Factory Exhaust Hardware

Many enthusiasts enjoy the appearance, fitment, and engineering of their original active exhaust system.

Instead of replacing the exhaust entirely, SST allows drivers to unlock additional control over the factory hardware already installed on the vehicle. This provides greater flexibility while retaining the OEM exhaust valves and their associated components.
