Noisy exhaust manifold i think

It sounds like you have a bad exhaust manifold. At cold starts it rattles and it will go away or less noisy as the car worm up. I think that might be the problem. Do you remember hitting a very bad pothole or perhaps driving over something that may have hit the manifold hard?
