I have the same car and exhaust, the valves will stay open pretty much all the time. I use the CG Precision VSC-1 valve controller so that I can control them if I want to quiet the car down a bit in the mornings, but besides that I usually leave them open. If you have bm3 you can actuate them within the app too.
