The exhaust system can be ordered in two different versions:
*With ECE approval*.
Only when choosing Bull-X Tronic controller
The ECE-approved exhaust system does not require a modification inspection and is approved for road use. While driving, you can choose between Comfort and Sport modes, how the valves operate. If your car has a driving mode selector, you can also control the valve operation that way. For vehicles without a driving mode selector, you can control the valve operation 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 in the open position. When the car is stationary, the valve is always in the closed position.
- Comfort mode: The valve is always in the closed position, 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 a switch, or valve control with a remote control, the product is not ECE approved.
Bull-X Tronic "Race" differs from the ECE approved model in that the exhaust valve can also be opened when stationary, but when driving, depending on the driving mode and throttle position, the valve is controlled in the same way as the ECE approved model.
