X-FLAP_features_EN_20260325

Built-in Delete Module|All-in-One Integration

The X-FLAP integrates an OEM signal decoding module directly into the main unit, eliminating the need for external delete devices.

Compatible with both single and dual valve systems, it ensures seamless ECU communication while minimizing DTC and warning light issues.

*After installation, clearing DTC codes is recommended.

Three Control Modes (ON / OFF / NOR)

In NOR mode, the system automatically corrects partial OEM signals to full open, ensuring optimal exhaust flow and sound performance.

*OFF mode should be used under low RPM and low load conditions.
