Exhaust valve control
With the ECE-approved version, the Bull-X Tronic controller allows Comfort or Sport mode to be selected. If the vehicle has selectable driving profiles, the valve can be controlled through this function. Vehicles without selectable driving profiles use the supplied button. Its LED indicates the valve status: the light is off when the valve is open and on when it is closed.
In Sport mode (Dynamic, Race), the valve remains open while driving within the ECE-approved operating range, but is always closed when stationary and between 20–80 km/h. In Comfort mode, the valve remains closed and opens while driving within the ECE-approved operating range when the throttle is opened by 75% or more.
Road use: ECE approval applies only to the combination with the Bull-X Tronic control unit with ECE approval and an EG-approved catalytic converter. Versions controlled by a switch, remote control or the Bull-X Tronic “Race” control unit do not have ECE approval and are intended exclusively for use on the racetrack.
Suitable for: SEAT Leon III (5F) / III (5F1), VW Golf VII (5G1).
