Generator exhaust rusted out

One of the joys of living in the Northeast--rust! I discovered that the exhaust pipe on my Onan 4000 generator has rusted through. :-( Do you think that a good muffler shop will be able to fix this, or should I take it to Cummins/Onan? I would think that the entire exhaust system on the generator will need to be replaced. This is on a 1998 Coachmen Class C motorhome. I use my generator a lot, as I dry camp at dog events. Any questions I should ask or issues to be identified before I take it somewhere?

    I would think a replacement exhaust pipe might be the best cure. Is the muffler threaded onto the pipe or is it welded?

    Any COMPETENT muffler shop can make and install a pipe & muffler that will outlast your rig!! Go there, show them the problem, get the options (with prices) and decide what to do!

    I recently had the experience of camping next to a large "A" rig (running both air conditioners - so they were inside)with a generator that sounded like a hot, hopped-up Honda reving the engine!!
