MPE and MPPK
I just recently upgraded my X5 with MPE and MPPK and the burble is extremely noticeable at sport mode even with the windows up. Like every time I slow down I can hear the exhaust popping in the trunk. It was so loud that my friend went like "geez what is rattling in your trunk??" Is this the same experience for the people with both the MPE and MPPK?

If you have popping in your exhaust when you lift off the throttle then somewhere you have an air leak in the exhaust.

Don't think its a leak. My 50i makes awesome burbles and blaps when I lift off of the throttle in sport mode and its bone stock aside from coding.
