1979 Honda CB750K · Exhaust Buying guide

Choose the sealing part for the identified exhaust joint

The cylinder-head-to-headpipe gasket and the separate exhaust joint gasket have different descriptions and OEM references. Use those details to identify the component needed, especially where the motorcycle has a changed exhaust.

Identify the gasket location before ordering

The headpipe gasket description identifies the cylinder-head-to-exhaust-headpipe joint. The other product is listed as an exhaust joint gasket for headpipe with a different pair of OEM references. Compare the part removed from the connection rather than treating the two gaskets as alternative versions of one item.

Check the exhaust fitted to this motorcycle

A motorcycle may retain its original exhaust layout or have a replacement system with different fittings. Use the individual listing and the removed part to assess the joint you are servicing. If the installed system is uncertain, provide photographs and its identifying details before selecting a seal.

Common questions

Is a headpipe gasket supplied as a set?

The featured cylinder-head-to-headpipe gasket is listed as one piece and sold individually. Count the joints you are servicing and order the quantity required rather than assuming one item supplies a complete exhaust service set.

What reference identifies the separate joint gasket?

The exhaust joint gasket for headpipe lists OEM 18391-425-000 and 18391-MJ4-000. Compare those references and the product photograph with the gasket removed from the connection you are repairing.

Can these seals be assumed to fit an aftermarket exhaust?

Check the installed system before choosing them. The product applications identify the motorcycle, while an aftermarket system may use different joint fittings. Compare the removed seal and system details or ask for help identifying the connection.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
