I installed the MPE a couple of weeks ago. It's significantly louder than stock. The volume level reminds me of my MPE on my old e92. Cold start is loud! There's no way to get around that. On throttle no matter what mode, it's got way more volume than stock. It also burbles and cracks letting off throttle. It doesn't drone and just cruising down the highway it's not invasive at all. I don't like the tone though, it's got the dreaded weed whacker tone. It just doesn't suit the X5 to me. I was hoping for something tonally like the m40i which sounds great. I'm going back to the stock exhaust...bummer.
