1980 Honda CB750K DOHC Exhaust Seals & Hardware

The 1980 CB750K exhaust selection is focused on seals and fittings rather than replacement muffler assemblies. Port gaskets, headpipe joint gaskets and individual Honda collars address different pieces of the installed DOHC exhaust, so identify the joint before choosing a part.

1980 Honda CB750K · Exhaust Buying guide

Start with the joint you are repairing

An exhaust port gasket and a headpipe joint gasket have different listings and OEM references. Compare the location and fitted parts first, then decide which seal or collar the repair actually requires.

Distinguish a port seal from a joint gasket

The port gasket lists references 18291-254-000 and 18291-MM5-860. The separate headpipe joint gasket lists 18391-425-000 and 18391-MJ4-000. Use those references and the old part to identify the intended connection. A shared exhaust category does not make the two gasket descriptions equivalent.

Plan around the exhaust actually installed

The verified products are described for the listed Honda applications. If the pipes have been replaced, compare their joints and fittings before buying stock-application pieces. A collar is sold per piece, and the gasket listings do not establish that every part required for an exhaust repair comes together.

Common questions

Are replacement muffler systems included here?

The verified selection for this model contains exhaust seals and hardware. No active complete exhaust-system listing was found in the assigned route. Review the individual products shown rather than treating the exhaust category as a complete-system package.

Is a joint collar also an exhaust gasket?

The collar is listed as genuine Honda hardware, sold per collar piece. The port and headpipe joint gaskets are separate products with their own references. Identify the component needed instead of choosing by the shared word joint.

How many port gaskets come in the featured listing?

The featured port gasket listing specifies one piece sold individually. Count the locations involved in your repair and order the quantity required. Do not interpret its broad Honda fitment list as a multi-gasket package.
