Mine is stock and I hear the bypass valve all the time.

I tend to shift around 2000 with normal driving. I think the auto with it’s 8 gears shifts at 1500 so maybe that’s why you guys don’t hear it.

I love the sound of the throttle burble when I’m decelerating.

I thought I was the only one who could hear it - like on the way to work it says 'only one more weekend before you put the snows on - call in sick and take off' or right now I can hear it saying 'it is 4:30 somewhere, come get me the hell out of this parking garage and lets go'.

I sold my MPPK airbox because I had a slot to grab an M2 at my dealer. That fell through so I'm back on the stock airbox and still have the M235. I can still hear some turbo whistle, about half as much as I did with the MPPK airbox.
