For vehicles without exhaust valves as standard - the valves in a Larini 'ActiValve' Exhaust Assembly will open and shut, and function, via the Larini pneumatic feed pipes.
The additional valve remote module kit, once installed, will allow the driver to remote activate the valves so they either a) stay open always (normal mode) or b) move to a closed position (quiet mode).
Installation of the valve control & remote kits must be completetd by a skilled automotive engineer/electrician.
PLEASE NOTE: The activalve and remote kits are only supplied with a Larini exhaust component.
