2022 BMW X3 M40i Stock Exhaust. Compared start up with the valve closed and after with the valve permanently opened. It is hard to capture on video but with the valve open on startup it is a little deeper and a little louder, in person there is a noticeable difference. Then some slight revs up to 4k. For the LCI they tuned out the burbles but there are some very minor burbles the more the car gets driven.
