Thanks man, I think this is the same sound that i was hearing with my v6 2012. It was right at gear changes and was pretty constant. I took it in today and they said they couldn't hear it, but someone in my thread pointed me here and I am glad they did! This is my first car and that noise was bothering me just a bit, but I am glad its not 'knocking' or detonation and the engine isn't slowly pitting itself.
Awesome work, I am really happy hearing this!
