1978 Honda CB400A · Exhaust Gaskets Buying guide

Map each gasket to its exhaust connection

The port gasket comes individually or in a ten-pack. Headpipe and crossover seals use different reference numbers for different joints. Check the fitted exhaust layout before ordering, especially when the system has been changed from standard.

Choose the correct joint family

The port gasket references 18212-634-000, 18291-236-000 and 18291-MN4-920. Headpipe and crossover seals use separate reference families. Compare the location and mating parts, because the common CB400A application describes the motorcycle rather than one interchangeable seal for every exhaust joint.

Separate package size from the repair quantity

The individual port-seal option supplies one gasket; the alternative package supplies ten. Work out how many port connections the repair disturbs before choosing between them. Headpipe and crossover seals remain separate selections and are not converted into a complete system set by adding port gaskets.

Exhaust Gaskets questions

How many gaskets are in the individual port-gasket order?

One. The individual item is explicitly supplied as one exhaust-port gasket. A separate ten-pack is available if that quantity suits the work; the ten-pack is not a statement of the motorcycle’s requirement.

Which reference distinguishes the headpipe joint seal?

The headpipe joint gasket uses 18391-413-000 / 18391-413-010. The crossover seal instead references 18392-413-000 / 18392-MG7-750. Use the joint location and original component to choose between them.

Will these seals fit a nonstandard exhaust?

Check the replacement exhaust manufacturer’s joint design and specifications. These CB400A applications do not guarantee compatibility after a collector, headpipe or muffler conversion, even if the system bolts to the original engine.
