Take control of your vehicle's sound with the Milltek Sport Exhaust Valve Controller, designed specifically for B58 Gen2-powered models including the BMW G42 M240i, G20 M340i, and Toyota GR Supra. This plug-and-play system gives you full manual control over your exhaust valves, allowing you to switch between quiet and aggressive exhaust tones at the touch of a button—independent of driving mode.
