Found this old thread and revived it. I've got a Z51 with fuse #42 pulled for open exhaust 100% of the time. Has anybody found a way to keep the 350 exhaust open 100% of the time. I've toggled the exhaust switch to sport and then started the car but it always starts in normal mode before it switches to sport.
