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.
My thought is the exhaust is contacting the body at some point. Have a muffler shop put it up on the lift to verify and correct the problem. Shouldn't be too much $$$.
get them to check the joint you had repaired too. it's possible that a piece of assembly paste might have fallen out which would cause the exhaust to blow at the joint. I have known it to happen on top of the exhaust which would cause it to blow onto the underside of the car. worth a look if it's on a lift anyway.
