1972 Honda SL350K2 · Exhaust Gaskets Buying guide

Buy the gasket quantity that matches the exhaust job

Both available products cover the same listed replacement references in different package quantities. Decide whether you need a small repair order or workshop stock before choosing the single piece or ten-pack.

Parts to consider

Choose quantity before choosing the package

The individual product supplies one gasket; the larger pack supplies ten. Count the positions being serviced and any spare stock you actually want. A ten-pack is a supply quantity, not the number required for one motorcycle or a complete exhaust-system parts list.

Compare the sealing joint on changed headers

If the exhaust has been replaced, compare its headpipe connection and gasket requirement before ordering. The two products share replacement references 18291-286-000 and 18291-286-306, but those references do not establish compatibility with every aftermarket joint. Use the exhaust maker’s information where the arrangement differs.

Questions before ordering

Does the ten-pack use a different gasket from the single-piece option?

Both products list the same replacement references, 18291-286-000 and 18291-286-306. The clear ordering difference is package quantity: one piece versus ten, so choose around the number of sealing positions and spares required.

How should I size an order for current work and spare stock?

Count the sealing positions in the planned repair first, then add only the spare gaskets you intend to keep. Individual pieces suit a counted small order; the ten-pack provides a fixed quantity for repeat work or workshop stock.

Will these gaskets suit an aftermarket header system?

Check the header’s connection at the engine and its specified gasket before ordering. Compare the replacement references and sealing arrangement; model-year selection alone does not verify every aftermarket exhaust joint.

Not sure which part you need?

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