1976 Honda CB550F · Exhaust Gaskets & Hardware Buying guide

Exhausts on restored motorcycles may differ from their original layout. Compare the engine-end pipes, clamp spacing and existing hardware before buying parts for the connection. The choices featured here are port gaskets and mounting pieces; they do not establish compatibility of a complete replacement muffler or every downstream joint in a modified system.
The single port-gasket product is sold individually and the linked pack contains ten. The separate hardware set contains eight studs, eight washers and eight nuts. Compare what is worn or missing before counting the order, and check the clamps separately rather than assuming the stud package includes them.
Use the number of port seals needed for the repair to choose the package. The individual product supplies one, while the linked ten-pack is useful for service stock or multiple jobs; it is not a four-piece vehicle package.
The stated hardware contents are eight studs, eight washers and eight nuts. Port gaskets and finned clamps are separate products. Inspect each part of the headpipe joint and add the items actually required for your repair.
Check the mounting at the engine, including the headpipe arrangement and clamp-hole spacing. The featured chrome clamp specifies 55 mm centres. A changed exhaust may use different fittings elsewhere, so compare the exact joint rather than selecting by model year alone.
