Finally, we are getting around to the mighty Sportster! First is the 2 into 1 pipe used from 1957 to 1965, 65454-57, we just finished a short run of these. They snap on the heads and are tight everywhere, just like the originals. We made the expanded end tip spot welded, also like original. Shown with our 65231-52 spot welded muffler, 65279-57 rear muffler clamp, and 65275-52 muffler to pipe clamp.
