Why ASR Component is the reference for flap control
Modern emissions and noise regulations force manufacturers to keep exhaust valves closed in many driving situations – even in "Sport" mode. The result is often a disappointing sound. ASR Component (known from the RX1/RX2 and CB2 modules) elegantly solves this problem via the CAN bus or the original actuators.
High-end technology for supercars & exotic cars
Anyone who Ferrari 812 Superfast, McLaren 720S or Lamborghini Huracan Drivers expect perfection. ASR Component delivers exactly that.
- Security: The modules respect component protection. Safety functions remain active at full load, while you enjoy pure sound at partial load.
- Exclusivity: We carry control systems for the rarest vehicles such as Aston Martin Vanquish, McLaren 765LT or the Mercedes AMG GT.
Performance upgrade for German premium brands
ASR's greatest strength lies in its broad coverage of top German models:
- Audi Sport: Maximum emotion for your RS3 (8Y/8V), RS6 or RSQ8.
- BMW M-Power: Unleash the sound of your M2, M3, M4 or the X5 M/X6 M Models.
- Mercedes-AMG: Whether C63, A45 or the luxurious G-Class – ASR restores the typical V8 or turbo sound to your AMG.
Fun for everyone: Hot Hatches
Even compact sports cars often sound too tame. With an ASR module, you can transform your VW Golf 7/8 R, Hyundai i30 N, Ford Fiesta ST or Cupra Formentor into a true character actor.
Functions at a glance
- Plug & Play: Installation is usually done via precisely fitting connectors directly on the actuator or in the trunk. No cables are cut, and it can be removed without leaving a trace at any time (perfect for leasing).
- SSA Memory: Saving the last setting (start-stop automatic).
- Cold start mode: Decide for yourself whether the car should start quietly (neighbor-friendly) or loudly ("cold start roar") in the morning.
- Original operation: On many models, you can use existing buttons (e.g., ESP button, driving profile selector, or cruise control) to control the flaps. No unsightly additional switches are needed!
Conclusion: ASR Component offers the technically cleanest solution on the market. Buy quality that also works in 300 km/h supercars.
