passenger side noise

  1. Flutter\Exhaust leak type sound [Video Attached] at full throttle

    2013 FX4 has sputter type sound only under full throttle (at 27 sec, 39 sec and 1:04 in the video). Does not make the noise in park so I'm assuming it's turbo related. Appears the passenger side mirror is amplifying the sound. It's extremely loud when next to wall or another vehicle. Anyone else...
