Originally used on the early Harley-Davidson Panheads and Knucklehead motorcycles, these 12" give your bike that nostalgic look. Chrome plated steel, sliding fit over 1-3/4" exhaust pipes. These flexible, slinky exhaust covers are sold individually. Made for Harley-Davidson FL 1941-65 and EL 1936-40, but looks great and works well on many motorcycles (including Shovelheads), great for custom applications as well as stock motorcycles.
