Vacuum Actuated Exhaust Throttle with Control Unit 70mm 2.75”

A complete kit providing full control over the exhaust sound. The combination of a 70mm vacuum-operated exhaust valve and an electronic controller with a built-in vacuum pump and remote controls allows switching exhaust modes at any moment – from quiet and comfortable to fully open, sporty sound.

The system operates independently of the factory vacuum source, making installation quick and non-invasive. Simply connect the controller to a 12V power supply and route the vacuum line to the valve.

Features:

• Remote sound control – open or close the valve with a single button (remote range 50–100 m).
• Built-in vacuum pump – the controller generates and releases vacuum independently of the engine.
• High durability – aluminum controller housing and heat-resistant components.

Kit includes:

• Vacuum controller unit (154 × 105 × 55 mm)
• 70mm exhaust valve
• 5 m vacuum hose
• 12V power harness
• External antenna
• 2× remote control
• T-fitting
