Mercedes Benz C63 AMG (W204) Armytrix Bolt-On Valvetronic Exhaust - Videos & Photos

@ Armytrix, (this may have already been answered).. Since they are vacuum controlled, I assume if the car is off then the valves are closed. Any way to get the valves to remain open for startup?

Hi there, thanks for your inquiry. Upon start up, the valves will be closed. However, if you want to have the valves open for start up, you can change the auto mode settings within our ARMYTRIX app. The valves are in auto mode by default, and by changing the rmp to below 1000 on auto mode, the valves will open upon start up.
