3800 exhaust issue
 

I have a 2002 bonniville that has what I beleive to be an exhaust leak on the back side of the engine. I have been unable to locate the leak. The leak is a fairly loud clicking type noise when the engine is cold. The noise goes away when the engine warms up. This engine does not have a donut type gasket where the header pipe connects to the manifold. Has anyone had this problem with their 3800.
