It is not welding to the case, the baffle is just spot welding to the pipe itself. Break the spot welds and just remove the first baffle. Drill 2" in end cap weld down spout, weld cap back on.had a few questions about the baffle inside. I was wanting cut off the end cap and make a new one to weld back on with a billet tip. does anyone know if the baffle is welded to the end cap.
