Frequently Asked Questions

How many Honda exhaust-pipe joint collars 18233-425-000 are included and required?

One genuine Honda half-collar, OEM 18233-425-000, is included. The listed four-cylinder CB750, CB900, CB1000 and CB1100 exhaust systems use eight half-collars in total—two around each of the four cylinder-head exhaust joints.

Are exhaust gaskets included with Honda OEM 18233-425-000?

No exhaust gaskets are specified. A four-cylinder engine uses four cylinder-head exhaust gaskets, one per port; inspect and normally replace them whenever the header is removed.

How are the half-collars installed without creating an exhaust leak?

Place two collars evenly around each pipe behind the flange, start the flange nuts by hand and tighten both sides gradually to Honda specifications. A cocked collar or uneven flange can prevent the gasket from sealing.
