Only when choosing the Bull-X Tronic controller
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 flaps operate. If your car has a driving mode selector, you can also control the flaps this way. For vehicles without a driving mode selector, the flaps can be controlled with the included separate on/off button. The button is backlit; when the light is on, the flaps are closed, and when the light is off, the flaps are open. The exhaust flaps operate within the limits allowed by ECE approval, regardless of the driving mode.
Bull-X Tronic offers two options for the exhaust flaps
Sport (Dynamic, Race): Within the limits allowed by ECE approval, the flap is always in the open position. When the car is stationary, the flap is always in the closed position.
- Comfort mode: The flap is always in the closed position, but within the limits allowed by ECE approval, the flap 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", flap controller with switch or flap controller with remote control, the product is not ECE approved
Bull-X Tronic "Race" differs from the ECE-approved model in that the exhaust flap can also be put in the open position when stationary, but when driving, depending on the driving mode and throttle position, the flap operates similarly to the ECE-approved model.
