I will get my Stinger in 1-2 weeks. I will keep it for a couple of days only before it will be picked up by one of the most exclusive and experienced exhaust manufacturers in the world. The task will be to develop a bi-modal exhaust that gives the Stinger an acoustic soul. Stay tuned for details... In fact the car will get an electronic system that opens and closes the valves. It can be modified through an iOS or Android Smartphone App (Bluetooth). The most common indicator for the valves control will be the rev. So my question to all of you who already own a Stinger 3.3 - what do you think which rev makes sense to define the point when the valves get opened? I think the best rev would be something between the rev before eco/comfort shift up and the rev when sport mode shifts down. What do you think?
