1971 Honda CB500K · Exhaust Buying guide

Order for the exhaust joint you are opening

A gasket seals an exhaust port; a clamp and its hardware retain the header. The rubber connecting tube serves a different joint in the original-style muffler assembly. One item does not replace the others.

Gaskets and mounting hardware do different jobs

The individual gasket and ten-pack list the same Honda reference numbers, but the pack quantities differ. The stud set supplies eight studs, washers and nuts; it does not include port gaskets. Check the clamp and associated collars on the motorcycle before deciding which hardware needs replacement.

Original-style joints need the right connector

The genuine Honda tube is listed for original-style CB500K muffler connections. Match OEM 18473-323-000 and the specific joint position; not every connector position uses the same rubber. An aftermarket exhaust layout may use a different joint and should be checked against its own components.

Exhaust Parts FAQs

How do the single gasket and ten-pack differ?

Both listings reference Honda 18291-216-000 / 18291-MN5-650. One listing supplies a single gasket and the other supplies ten. Choose by the number of ports being serviced and whether you want spare gaskets.

Which measurement should I take before choosing a clamp for custom headers?

Compare the clamp’s 55mm mounting-hole center spacing with the fitted header arrangement. Also check the collars and flange hardware. Its 14-fin appearance and CB500K application do not establish compatibility with a changed exhaust.

Can I order the same connector rubber for every muffler joint?

Match Honda 18473-323-000 to the individual joint position and pipe diameters. The original four-muffler system uses several connector rubbers, but the listing warns that not every position uses this same Honda number.
