I can hear what I think is an exhaust leak when I drive beside concrete barriers, guard rails, etc. It's kind of a loud ticking sound. The muffler and the pipe between the turbo and muffler seem to...
Even if it's just an exhaust gasket, on a 03 engine I'd probably replace the manifold while apart. The labor of getting it off/on will be more than the cost of a new manifold if non of the bolts break. Not sure if I'd go with one from China.
