*With ECE approval*
Only when choosing the Bull-X Tronic control unit
An ECE-approved exhaust system does not require a modification inspection and is approved for road use. When driving, you can choose between Comfort and Sport modes for how the valves operate. If your car has a driving mode selector, you can also control the valves that way. For vehicles without a driving mode selector, the valves can be controlled with the included separate on/off button. The button is backlit; when the light is on, the valves are closed, and when the light is off, the valves are open. The exhaust valves are controlled within the limits allowed by ECE approval, regardless of the driving mode.
Bull-X Tronic offers two options for the exhaust valves:
- Sport (Dynamic, Race): Within the limits allowed by ECE approval, the valve is always open. When the car is stationary, the valve is always closed.
- Comfort mode: The valve is always closed, but within the limits allowed by ECE approval, the valve opens when at least 75% throttle is applied while the car is moving.
*Without ECE approval*:
If you choose one of these three options, Bull-X Tronic "Race", valve control with switch or valve control with remote control, the product is not ECE approved
Bull-X Tronic "Race" differs from the ECE-approved model in that the exhaust valve can be opened even when stationary, but when driving, depending on the driving mode and throttle position, the valve operates like the ECE-approved model.
