CETE Active Valve Control Module (Exhaust Valve Controller) for Audi S6, S7 C8 (2019+)
TAG Motorsports is pleased to offer the CETE Active Valve Control Module (Exhaust Valve Controller) for Audi S6, S7 C8 (2019+).
With this CETE Automotive exhaust valve control module you have the ability to better control your exhaust valves for specific situations. The controller allows you to keep the exhaust valves open fully in the dynamic drive select setting at all RPM. The exhaust valves will also automatically be set to dynamic when the car is started if it was shut-off in dynamic mode.

The full drive select system stays intact and functional, plus no added key fobs or controls are needed.
