The exhaust repair choices for the 1978 CB750F include port gaskets, retaining clamps, a stud-and-nut set and a Honda collar. Work from the component that needs replacement. Their shared application does not make them a complete exhaust installation package.

1978 Honda CB750F · Exhaust Buying guide

Build the order around the component being replaced

A gasket addresses the listed sealing connection; studs, nuts and clamps are separate retaining components. Check the fitted exhaust and compare each product reference before deciding which items belong in your repair order.

Read the supply details for each component

The port gasket and flange clamp are sold each. The stud set explicitly contains eight studs and eight flange nuts, while the collar is sold per pictured collar piece. Count the parts required for your repair instead of assuming every exhaust listing supplies a motorcycle-wide set.

Check retaining pieces against the exhaust now fitted

The clamp lists reference 18231-392-000 and the Honda collar lists 18233-392-000. Compare the existing fittings, particularly with a changed exhaust. These references do not establish the dimensions, hardware or connection arrangement of an aftermarket pipe assembly, which needs its own application check.

Common questions

Are mufflers or complete pipes included with these products?

The products shown are gaskets and retaining components, with their own supply descriptions. They are not described as complete pipe or muffler assemblies. Plan any larger exhaust replacement from the full requirements of the system being fitted.

Does the stud set also supply port gaskets?

The stated contents are eight exhaust studs and eight flange nuts. Port gaskets and flange clamps are separate listings. Add those components only after checking what the repair requires; the hardware description does not make them part of the set.

How is the Honda collar supplied?

The collar is sold per pictured collar piece. Compare reference 18233-392-000 with the existing hardware and determine the individual pieces required for the job. That sold-as wording does not establish a full-bike collar set or a supplied clamp.
