The M.A.C. chrome slip-on pair is a muffler option for the 1980 CB900C Custom’s factory-style exhaust layout. Before ordering, inspect the existing headers, joints and supports. A custom exhaust fitted by a previous owner may require different connections or mounting work.

1980 Honda CB900C Custom · Slip-On Mufflers Buying guide

Confirm the exhaust layout before choosing slip-ons

The listed mufflers have chrome flare tips and all-steel baffles. Their Custom application should be checked against the actual retained pipes and mounting points rather than assumed from appearance alone.

Parts to consider

1980-82 Honda CB900C M.A.C. Chrome Slip-On Flare Tip Muffler Set M.A.C. chrome slip-on mufflersPair of flare-tip mufflers with all-steel baffles, listed for the CB900C Custom’s factory-style exhaust arrangement.View part

Inspect the parts that will stay on the bike

Slip-on selection depends on the existing pipe arrangement and supports. Check those pieces before buying the muffler pair, especially where repairs or alterations are visible. The motorcycle model by itself does not establish compatibility with every aftermarket header system.

Confirm the slip-on connections and baffle scope

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.

Buying 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.

What baffle construction is described?

All-steel baffles. Confirm whether internal service is supported and which parts and procedure are required before planning baffle or packing work; no replaceable packing kit is specified here.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
