1982 Honda CB750SC · Exhaust Gaskets Buying guide

Count individual exhaust sealing rings

These are cylinder-head-to-headpipe sealing gaskets. They are separate from exhaust retainers and mounting hardware, and their individual quantity should be distinguished from four-piece contents in some engine gasket packages.

Use the correct joint reference

The featured gasket replaces reference 18291-MM5-860 at the headpipe-to-cylinder-head connection. Compare the exhaust arrangement before ordering. A changed exhaust may have different joints further downstream, and this headpipe gasket does not establish fitment for those other connections.

Avoid duplicating kit contents

Some of the early Nighthawk engine gasket packages list four exhaust headpipe gaskets. If one of those packages is already being ordered, check its full contents before adding loose rings. For a localized repair, individual gaskets can be counted against the actual ports being disturbed.

Exhaust Gaskets questions

Does one purchase contain four gaskets?

No. The featured listing supplies one headpipe gasket. Four-piece exhaust gasket quantities appear in some larger engine packages, so keep those kit contents separate from an individual product purchase.

Are mounting collars supplied with the gasket?

The gasket product describes the sealing ring only. Inspect and identify retainers and mounting pieces separately; package contents should not be inferred from the wider category title.

Why are there two similar gasket choices?

Both individual listings share the 18291-MM5-860 replacement reference. They are alternative catalog entries for the described headpipe joint, so compare the products rather than assuming both are needed together.

Not sure which part you need?

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