Ok so today I drove home in sport mode..."very easy" to abide by the break in rules and the exhaust was open when I pulled into the driveway. I looked up the exhaust and it was barely cracked open so I guess it opens and closes based on a bunch of parameters. All i know is that it never opened in comfort mode driven easy. At least I know it works....
