I'd say not a knock or ping, but more of a rattle clank. but went away pretty fast. And they have had it all week so that was the only time i've heard it

Yeah my buddy is back home who is a much better mechanic than I, so I think together we might tackle the exhaust man. Side note: After I got the pathfinder back from the repair shop I was driving it to work the next day, pulled up to a stop sign and could here some nasties coming from the engine. This was a new noise and not the exhaust. They have had it all week long and have not been able to pin point the sound. It is there on cold starts but goes away quickly. He has pulled everything back off to check his work and says there was nothing wrong, including the cover bolt being in the right places. My question is would there be anything in the engine that would let go by replacing the timing belt? they also did pulleys, bearings and waterpump at the same time.

Yeah thats what I thought, are the headers a direct replacement? Cost? and how hard is it to remove a brocken bolt?

Can I hurt anything by running with a leaky exhaust manifold? I know it has been leaking for awhile and would like to fix it but money is tight and if I can put it off that would be better

So I woosed out and took my 95 pathfinder to the local shop to have the timing belt done this morning. I also asked them to diagonse the Ticking noise i've been hearing. Well turns out the noise is a broken bolt on the exhaust manifold. Guy told me $75 bucks to have the manifold decked flat and $250 to remove and replace plus an hour labor per broken bolt. Does this seem high to anyone? Thanks
