There was only one bolt to install the muffler
There was only one bolt to install the muffler and no lock washers. My muffler keeps vibrating loose. Now I will have to order (1) bolt and try and find some lock washers. Your pictures are incomplete. You call it an assembly, then why isn't everything there to install it. Must have been done by somebody in an office who doesn't have clue about repairing things.
