1982 Honda CB900C Custom Exhaust Parts

Exhaust work on the 1982 CB900C Custom can range from renewing a port gasket to replacing the rear mufflers. Check the system fitted before ordering: the M.A.C. flare-tip pair is listed for factory-style muffler replacement, while modified pipework needs its own fit checks.

1982 Honda CB900C Custom · Exhaust Parts Buying guide

Separate muffler replacement from port sealing

The chrome slip-on pair and individual headpipe gaskets serve different repairs. Compare the installed exhaust arrangement, mounting and the joints being opened before assembling a replacement order.

Count the exhaust-port seals for the repair

Each featured headpipe gasket is one exhaust-port seal. Resealing all four cylinder-head ports needs four individual gaskets; remove the old crush seals from the disturbed joints first. The seals do not replace the joint half-collars, studs or nuts, which need separate inspection.

Check the retained system before choosing slip-ons

The M.A.C. 001-3111 pair is a slip-on replacement for the original-style CB900C exhaust arrangement. Confirm the retained headpipes, balance box, connecting joints and mounting supports before ordering. Its all-steel baffle description does not establish a separate serviceable packing kit or compatibility with an unrelated full-system header.

Exhaust Parts questions

Will these slip-ons replace a complete aftermarket 4-into-1 system?

They are a paired slip-on set intended for the original-style CB900C arrangement. An aftermarket collector or header can have different outlets and supports. Identify the retained system and confirm those connections before treating the pair as a complete-system replacement.

Does the no-rejetting description cover a modified intake and exhaust?

That description applies to the intended stock-style installation. It does not establish a fuel-setting plan for changed air filters, headers or other engine modifications. Assess the complete installed combination instead of choosing jets from the muffler finish or a general fitment label.

Will an exhaust-port gasket seal a leak at the muffler connection?

Locate the leak before ordering. These individual gaskets seal the headpipe-to-cylinder-head ports. The slip-on connections farther back use their own joint arrangement, so an exhaust-port gasket is not a universal seal for every exhaust leak.
