11th gen SI buzzing sound

[Maxfarace]

I've had this buzzing sound for a while now, but recently it's gotten a lot worse. Happens when the engine is warm and doesn't matter if I'm on or off the throttle. I've also been able to recreate the sound in neutral revving the engine - just can't figure out where it's coming from. Only happens in 1st and 2nd gear between 2500 to 3000 RPM. This video was right at 2500 RPM 2nd gear. Anyone know what this could be? Scanner showed no codes. I do have a few mods. Intake, turbo pipe, intercooler.

I have the same thing and I think it's the high pressure fuel pump taking a shit

Does yours sound like it's coming from the rear? Mine sounds like it's coming from the engine bay, buy I could be wrong.
