Hello everyone, i have a 2016 Yukon slt and last week i started to hear this sound.
The sound appears when i accelerate at 1K RPM when stationary or driving, and sometime at 1.5K RPM but only while driving.
And i think i heard it on cold starts.
I filmed a video of the adaptive valve after the muffle but it had nothing to do with it.
Video of the sound ^
