Lol! Yeah the dealers are clueless. Probably had no idea there even were valves. We literally wired them open. No loss of back pressure or anything crazy. They are there purely to mute sound. BMW has them set to open according to throttle rather than RPM and also on cold start from what I understand. My performance guy is a guru. He did this to his own F10 as well. Sounds really nice and throaty and refined without giving you an obnoxious noise like you get with most aftermarket exhausts and there is none of the common torque loss either. PERFECT solution. Nothing massive. Just nice and clean and a subtle but aggressive sounding note difference from stock. My guy is also working on custom classy looking tips as well. I will post a thread when he has them.
