I have an exhaust pipe leak near the exhaust manifold on my 2004 Intrepid ES. Any suggestions on how I should repair/replace the exhaust system without replacing everything and spending a grand?

were going to need a better description of the location. maybe use a pen to point at where its coming from in a photograph.
not trying to be a jerk, but here's why:
1:aluminum heads
2:cast iron headers
3:catalytic converter

none of those materials will lend well to band aids, jb weld, epoxy, etc.
my assumption is one of:
1:exhaust gasket leak
2: vband loose, and or broken at the joint.

other options are actual cracked headers. and on a 13 year old car its possible.

could you explain more, what sounds is it making, why you think its leaking. does it smell like exhaust under the hood?

Excellent post by zerokool. One more common failure point is the flex joint a little more down stream from the cat.

You might do the Sea Foam tune-up where you port some Sea Foam (auto part store item) into the little plastic vacuum elbow just forward of the center of the throttle body thru the right size vinyl tubing (from Lowes or similar) with the engine running a little above idle - let it ingest about half a can (not too fast or you could hydrolock the engine and do some damage - control flow by squeezing the plastic tube down with hemostat or pliers or by partially kinking) - then increase the rate of flow gradually until the engine stalls out. Let it soak with engine off for 20 to 30 minutes, then start it up.

When you start it back up, the exhaust will smoke *very* heavily (so much so that the neighbors may think your car is on fire - seriously) because the Sea Foam dissolved a lot of carbon in the valves and cylinders (a good thing) and it's burning and coming out the exhaust, but related to your problem, heavy smoke will also come out of any leaks along the exhaust to you can easily visually pinpoint the leak.

leave it to peva to always find another way. lol.
that smoke leak method actually sounds effective.
LOL! I found that one by accident when I did the Sea Foam Italian tune-up. I got smoke out of the V-band joints - didn't even know they were leaking (probably some of that in all of our cars). At first I thought something bad was happening.
