Vacuum Actuated Exhaust Throttle with Control Unit 51mm 2”

A complete kit providing full control over the exhaust sound.
The combination of a 51mm 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.
