These new mufflers were obtained by going to a local Harley Davidson Dealer and inquiring as to what happens to old parts when someone has new after market installed. He told me they are kept in a discard bin for ten days and then thrown out! These were practically new and did not cost me one cent!
Start by taking a piece of flat bar about 11 inches x 1.25 inches and drilling holes to match the muffler brackets.
Bolt on to the new mufflers.
After slipping on to the headers, mark holes for drilling to fit the existing brackets and you have a NEW SOUND!
