1971 Honda SL350K1 · Exhaust Buying guide

Plan the port-sealing order before pipe work

Both gasket packages carry the same replacement references. Their useful difference is quantity supplied. Inspect the exhaust assembly first so that your order also accounts for any separately required retaining or mounting pieces.

Choose quantity by the work planned

The individual product supplies one exhaust-port gasket and the multipack supplies ten. Both carry references 18291-286-000 and 18291-286-306. Count the joints you are servicing and any deliberate workshop spares separately, rather than treating the pack quantity as a motorcycle requirement.

Check why the joint needs attention

Inspect the pipe seating and retaining hardware when planning a sealing repair, especially if replacement pipes have been fitted. Use the appropriate instructions for preparation and fastening. A fresh gasket should be selected as part of that assessment rather than as a substitute for inspecting alignment.

Buying questions

Is there a fitment difference between the single gasket and ten-pack?

Their descriptions give the same replacement references and application range. The documented difference is package quantity: one piece or ten. Choose according to the repair and any spares you want to keep.

Can I assume this gasket works with any aftermarket exhaust?

Check how the replacement pipe seats at the cylinder head and follow the exhaust maker’s requirements. The motorcycle application alone does not establish the sealing arrangement of every aftermarket system.

Should I buy extra gaskets before removing the pipes?

Plan the work and identify the joints that will be disturbed first. The single-piece option supports a specific repair quantity; the ten-pack makes sense when you deliberately want additional service stock.

Not sure which part you need?

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