1982 Honda CB900C Custom · Exhaust Gaskets Buying guide
The featured sealing piece fits the cylinder-head-to-headpipe joint and references 18291-MM5-860. Choose it for that location rather than using an exhaust-category label to identify every gasket in a modified system.
The featured gasket is sold individually for the headpipe-to-cylinder-head port. Four are needed when all four ports are resealed. Remove each old crush gasket from a disturbed port before fitting its replacement, and inspect the seating surface rather than stacking a new gasket over the old one.
One purchased gasket supplies one sealing piece. Count the joints being disturbed, and inspect their seating surfaces and fastening hardware before reassembly. Use the service manual for the installation sequence and specifications rather than assuming a new gasket alone resolves damaged mounting parts.
No. Remove the old crush seal from the disturbed port and inspect the seat before fitting a fresh gasket. A compressed old ring can be easy to overlook; stacking seals is not a substitute for preparing the joint properly.
No. The 18233-425-000 product is one joint half-collar, with two used at each cylinder-head pipe joint. The gasket seals inside the port. Match the missing or damaged piece before ordering either product, and inspect the studs, nuts and flanges separately.
Inspect the studs, nuts, cylinder-head threads and retained pipe flanges first. The gasket serves a separate sealing job; damaged fasteners or threads need their own repair, but opening a joint alone does not prove that every stud must be replaced.
