Re: '96 3.1 exhaust leak?

When you get leaks like that which go away as it warms up it's usually a cracked exhaust manifold...slightly loose mainfold to head mounting bolts will seal up as the engine warms too, but makes a sharper clicking type exhaust noise, not a rumble.

It's possible it's leaking at the connector between the pipe and manifold too...they can get loose or break a stud and act like that
