1982 Honda CB900F Supersport · Exhaust Joint Parts Buying guide
The crossover gasket is a year-specific choice here, while headpipe seals are sold one at a time. Compare the fitted exhaust connections and inspect their fasteners before building a complete service order.

Match the 18391-461-000 crossover gasket to the fitted 1982 F connection, and identify headpipe and muffler-joint seals separately. Compare the removed part and actual joint dimensions after any exhaust change; the three names do not describe interchangeable seals.
Inspect stud threads, flange nuts, collars and the exhaust supports while the system is accessible. The stud package contains eight studs and eight nuts but does not repair stripped cylinder-head threads. Resolve damaged threads and misalignment before fitting new seals or applying the specified tightening procedure.
Identify the connection being opened and compare the removed part, joint dimensions and replacement reference. The head-to-headpipe seal sits at the cylinder head; a muffler-joint or crossover seal serves another connection. Similar category names do not make them interchangeable.
No. Inspect both the studs and the threaded holes. A stripped or previously repaired hole needs assessment and a suitable thread-repair plan before new hardware is fitted. Do not force a new stud into damaged threads or compensate with extra tightening.
Check that the correct seals and collars are seated and that the headpipes, joints and mounting brackets match the fitted system. Support and align the assembly according to its service procedure before tightening. Do not pull a misaligned exhaust into place with the studs.
