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 flap operation with it. Vehicles without a driving mode selector can control the flap operation 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.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan\u003eBull-X Tronic offers two options for the exhaust flaps:\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan\u003e- Sport (Dynamic, Race): Within the limits allowed by ECE approval, the flap is always in the open position.
