1983 Honda CB550SC Exhaust Gasket Choices

1983 Honda CB550SC · Exhaust Buying guide

Choose the seal for the exhaust connection being serviced

The two port-gasket packages share three replacement references. The crossover gasket has its own references and function. Package size determines supplied port-gasket quantity; it does not identify another exhaust joint or the motorcycle’s required seal count.

Related parts: Exhaust port gaskets supplied in a ten-pack

Choose the port-gasket package from your required quantity

Both port-gasket listings identify the same three replacement references. The individual item is explicitly sold each, while the pack supplies ten. Choose between them from the number of seals you need, keeping supplied quantity separate from any assumption about an entire exhaust service.

Give the crossover joint its own reference check

The crossover gasket identifies 18392-413-000 and 18392-MG7-750, instead of the port gasket’s numbers. Compare that separate component with the joint being serviced. Its description does not state a package count, so confirm the supplied contents where quantity affects your order.

Common questions

Are pipes or mufflers included here?

The products shown are port and crossover gaskets. None is described as a pipe, muffler or complete exhaust system. Plan those replacement assemblies separately from the seal choices.

Do the single gasket and ten-pack serve different locations?

The descriptions call both products exhaust port gaskets and give the same replacement references. Their stated difference is supplied quantity. The crossover gasket is the separately named seal, with a different set of references.

Does the crossover gasket come as a pair?

Its description identifies a crossover gasket and two replacement references without specifying a supplied pair or package count. Confirm the contents before ordering; two references should not be read as two included gaskets.
