1979 Honda CB750F Exhaust Parts & Mufflers

Exhaust work on the 1979 CB750F may call for port gaskets, muffler-joint seals, mounting hardware or replacement silencers. Start with the system fitted to the bike: stock-headpipe slip-ons and original-style joint parts need separate checking when an aftermarket exhaust has replaced it.

1979 Honda CB750F · Exhaust Buying guide

Separate exhaust sealing from muffler replacement

Choose parts for the joint or component being serviced. Headpipe gaskets seal at the cylinder head; muffler-joint gaskets serve another connection. The M.A.C. mufflers have a stock-headpipe application, rather than universal exhaust fitment.

Order the seal for the actual joint

A cylinder-head port gasket and a muffler-joint gasket address different connections. Compare the removed seal and current pipe arrangement before ordering. The featured port gasket is supplied individually, as is the genuine Honda collar; count the pieces needed for your repair rather than assuming each order covers the whole exhaust.

Check modified systems before choosing slip-ons

The M.A.C. megaphones are replacement mufflers for stock headpipes, so an aftermarket header may change their suitability. Compare the inlet connection and mounting arrangement before ordering. For a changed exhaust or intake combination, follow the component maker's tuning guidance rather than assuming a universal jetting result.

Exhaust buying questions

Which gasket do I need for a leak at the cylinder head?

Compare the cylinder-head-to-headpipe port gasket, rather than the muffler-joint gasket further along the system. The featured port gasket is sold individually; order the number needed for the ports being serviced.

Will the M.A.C. mufflers fit an aftermarket header?

Their confirmed application uses stock headpipes. A replacement header can change the inlet and mounting arrangement, so compare the actual exhaust and obtain confirmed compatibility before treating these as a suitable slip-on choice.

Are the pipe-joint collars supplied as a complete set?

The genuine Honda collar is sold individually, with reference 18233-438-000. Compare the existing joint hardware and count the collars required for your particular repair before selecting the order quantity.
