Have a very good right and left muffler for a early I guess a black bomber cb450. I am working on a 1968 cb450 for someone and it only has the right side correct muffler but in the spare parrts there is a pair right and left muffler for an earrlier model. The earlier mufflers have a ear to mount it about 4.5 to 7.5 inches back from the front of the muffler. I would like to sell or trade these for a good muffler that does not have the mounting ear. I will be posting pictures of these.
