Is the Muffler/Exhaust supposed to be welded to the exhaust pipe or is it just supposed to be inserted and be able to move around. The exhaust pipe on my LT1045 has become disconnected from the exhaust/Muffler and I just need to know if I should just replace or attempt to repair. If I replace I would imagine I would need the entire assembly, Pipe and Muffler welded together. Any thoughts would be much appreciated as well as a good supplier for the parts.
