A couple of questions and few things to check:
What year is your car?
Auto or manual?
Mileage on your car?
A few things to check:
I had a similar rattle. There is what I call a mesh hinge that allows the exhaust to move in 2 different pieces. It should be within the area of the passenger door, underneath the car. These rings on mesh hinges that hold the mesh to the pipes tend (especially if you have a Solo exhaut) to come loose. Check that part first!!!!
It honestly sounds like you have something loose on your exhaust/turbo somewhere.
One of the reasons I asked what year your car, is that it could be your timing chain... But I would guess it's more something loose.
