I have a 2016 Mustang GT and it makes a noise identical to the ones in linked videos. It has kooks longtubes corsa catback cai and a tune. The noise was present even before mods, but now that I am starting to modify it, it is beginning to worry me. The noise only happens at idle after start up, and goes away with RPM but returns when back to idle, it can be heard from the drivers side tire and it doesn’t happen all the time. Only somedays and at random. Can’t exactly pinpoint the condition it happens most. Can anyone please provide insight as to what the noise is and why it is being caused, it would be greatly appreciated.

Check for exhaust leaks, and also inspect the pullies.

No exhaust leaks, happened even before the headers, and thoroughly checked for leaks after headers, even had a shop check for leaks, said I did a great job with the install. When opening the hood you can’t hear the noise coming from the front of the motor, just from drivers side tire, or from underneath the car.

Now I'm lost. I have no idea what the noise could be. I would need to put my hands on the car.

It sounds almost like it’s something in the rotating assembly..
