well i just had to totally redo my exhaust (although im just really learning about cars, i mean i can change oil, but exhaust was totally new!) with the help of my dad, and i think the pipe your are talking about is the head or front pipe?
its not one long pipe from the manifold to the back, its a front pipe into the catalytic converter, then from that to the muffler i think, then another pipe from the muffler to the back where the exhaust comes out (tail pipe).
so i guess depending on where the break is, maybe you can just replace that part of pipe? im not positive, but hope this helps.
