Why manual flap control is the best upgrade
Modern sports cars (like BMW M, Mercedes-AMG, or Porsche) often have a problem: even in "Sport" mode, the exhaust flaps don't always open fully. In certain RPM ranges or gears, the software closes the flaps to comply with noise regulations. The result? The sound is "reduced." Our control modules remove this limitation.
ASR Component: The reference for flap control
The modules of ASR Component (e.g. the RX1 or RX2 series) are known for their extremely high quality and easy installation.
- Function: You control the flaps via a supplied remote control or – even more elegantly – via the existing buttons in the vehicle (e.g. driving profile switch).
- Start mode: You can program whether the flaps should always be open, always closed, or in their standard state when the engine starts (control cold start noise!).
- Vehicles: Available for almost all premium models such as Mercedes-AMG (C63, GT, SL) BMW M-models, Porsche 992, Ferrari (F8, 812) and many more.
LEIB Engineering: CAN bus professionals
In addition to pure flap control, we offer specialized solutions from LEIB Engineering to.
- CAN Exhaust Pro: These modules integrate invisibly into the vehicle's CAN bus and allow control via original buttons.
- OPF Delete: For motorsport we offer LEIB OPF Delete Kits These prevent error messages in the on-board computer if the gasoline particulate filter (for track use) has been removed.
Installation & Reversibility
A huge advantage of our systems is the Plug & Play InstallationThe modules are plugged in between the original wiring harness and the actuator using suitable connectors. In most cases, no cables need to be cut. This means the system can be removed without leaving a trace at any time – ideal for leased vehicles.
