Ah, the dreaded 460 exhaust leak. If you are lucky it is only the pipe but these engines are notorious for cracked manifolds and broken manifold bolts. Just be prepared for it.
Best fix is replacing the restrictive manifolds with headers. It is not cheap but you'll gain some serious power as well. That is what I did and I'd do it again. Best of luck!
