the car has a harmonic exhaust drome that starts at 1100 RPM then vibrates through entire car does not go away with speed. The drone stares weather or not vehicle is driving or static. There was broken bolts and gasket replaced in the last month so I've been told. I believe that there's a counterbalance weight messing off the exhaust system.
