If you pull the plugs when they are open, they will stay open. I just used BimmerLink to open them and then unplugged. I ran that for a bit and didn't really notice a big difference.
Also consider there is a significant amount of sound deadening in the vehicle, it's much louder outside than you would think. I noticed when i had the fuse box cover off after i installed my hitch it sounded much louder.
I have a 50i with M-Sport exhaust, which is more almost the same as m50i. I've also been looking at options trying to figure out what can be done.
Dahler has an exhaust that sounds really good, with manual control of flaps, but it's $5k.

how much was the m-sport exhaust and installation cost? also can u please share some pics of how it looks?
