No, because the exhaust pipe has a couple of unique bends to clear the frame cross member. You might be able to piece together the front half of a new Jeep pipe with the back half of your existing - but only if the new pipe has the same bend off the manifold as the old. There's isn't much room for the pipe so whatever you use, it has to be a very close match.
