ARMYTRIX Valve Control Technology

• Effortless Mode Switching Between Loud and Quiet: With a simple press on the ARMYTRIX remote or through the smartphone app, users can switch between exhaust modes effortlessly to match their preference.
• Personalized Automatic Mode for Smooth Driving: The automatic mode adjusts the exhaust valve based on a preset RPM range or turbo pressure, eliminating the need for manual input. Users can customize these automatic settings to fit their driving style perfectly.
• Enhanced Power Without Sacrificing Torque: Depending on the vehicle, modifications, and tuning, opening the valves enables unrestricted exhaust flow by bypassing muffler constraints. When closed, the valves maintain back pressure at low RPMs, preserving torque commonly lost in straight-pipe setups.
• ARMYTRIX Valve Control Remote: Featuring a high-gloss, piano-black finish, this remote offers a sleek, minimalist aesthetic.
• 3 Modes:
  • Smart mode
  • Neighbor mode
  • Beast mode
• Smart Assistant App: Connected via Bluetooth to the OBDII device, the ARMYTRIX mobile app provides remote valve control and real-time monitoring of car metrics such as RPM, speed, and fuel levels. In auto mode, users can set a specific RPM threshold to activate the valve.
