1985 Honda CB450SC Nighthawk · Exhaust Buying guide
The exhaust-port choices share a replacement reference family and offer individual or ten-pack quantities. Headpipe-joint and crossover gaskets use different Honda references. Keep those locations distinct when assembling a repair order, including any exhaust changes that affect the required seal.

Record the actual exhaust location with the full replacement reference. A port gasket belongs with the cylinder-head connection; the headpipe-joint and crossover products belong with their own named applications. This makes a request for advice more useful when an old order or removed part has only a short gasket description.
For the port references, you can buy one gasket per item or a pack containing ten. Choose the format after deciding the required repair quantity and any intended spares. Joint and crossover descriptions do not give a package count, so obtain that detail before converting a connection list into an order.
Identify the exhaust port and give the applicable Honda reference: 18212-634-000, 18291-236-000 or 18291-MN4-920. Both port-gasket formats list these numbers. Then state the quantity required so it can be compared with individual or ten-pack supply.
Describe the actual joint location and the replacement exhaust’s required seal dimensions. Include the relevant Honda reference where it applies. Headpipe-joint and crossover listings do not provide measurements, so model application alone cannot settle every changed connection.
Compare the immediate port-gasket requirement with any spares you intend to keep. The ten-pack supplies ten of the listed port gaskets; individual items supply one each. Select the package that matches that total, without assuming a complete exhaust-seal assortment.
