How so? Warm up the car, take off the belt and go for a 5 min ride. You will know for sure if it's belt /pulley related or not.

Takes some time to do things like that I don't really have a garage.
The sound is resonating through the exhaust. I'm about to take it to a dealership see what they say.
I brought the car to a Indy mechanic who has been in the game for 50years and he was blown away from what the sound was.
Still looking for the source of the sound.
