1975 Honda CB750K · Mufflers, Baffles & Packing Buying guide

Identify the muffler before choosing a baffle or shield repair

The individual baffle is listed for stock-type 1972–75 CB750K mufflers. The 341-style reproduction set has fixed internal baffles, so its model application does not establish compatibility with that loose insert.

Parts to consider

Match the loose baffle by its references

The individual baffle replaces 18311-341-900 and 18311-341-901. Use those references and the fitted muffler construction for comparison. The reproduction set’s non-replaceable internal baffles rule out assuming a shared insert simply because both products include 1975 in their application.

Choose a new shield or renew the retained shield’s hardware

The heat-shield product includes one shield with its fixing pieces. The separate hardware-only package serves one retained shield, supplying three screws, three metal washers and six fibre spacers. Select the package that matches the part being reused.

Common questions

Is the loose baffle supplied as a pair?

It is sold individually. Count the suitable mufflers needing inserts rather than assuming one order covers the whole exhaust.

How much hardware comes with a new heat shield?

One shield comes with three bolts, three washers and six spacers. The stated application calls for two shields when replacing both; each product package covers one shield.

How much of the connecting joint does one tube set replace?

It contains one tube, one band clamp and one screw. Two sets are specified for the listed exhaust application; choose the quantity needed for the joints being renewed.
