Has anybody tried the Gravely 018543 muffler onto their machine? I think I am going to give it a shot on my 16/6 Tecumseh and am looking to see if anyone else has done this. I know the inlet size is different but nothing that can't be overcome easily. The overall size is similar to what was on the tractor originally, or at least when I got mine. Heck, it can even be oriented for a mini stack.
