This is a remote control that allows you to freely open and close the muffler valve on Abarth 595 and 695 models from Series 5 onwards. Installation is complete by inserting this product into the original connector and drawing constant power from the battery. It's a simple plug-and-play installation, so you won't damage the original wiring. The main unit can be attached inside the engine compartment with double-sided tape. Normally, even in Scorpion mode, the valve closes at 5-60 km/h, but by installing this unit, you can freely control the valve opening and closing. You can open the valve fully across the entire range. Remote on: Valve always open Remote off: Valve closed (original control) The valve operation is memorized even when the engine is turned off and remains until the next time the engine is started.
