Frequently Asked Questions

How many Honda CB750K muffler baffles are included and required?

One stock-type muffler baffle replacing Honda OEM 18311-341-900 and 18311-341-901 is included. The listed CB750K uses a four-muffler exhaust, so four baffles are required to replace all four.

Will muffler baffle 18311-341-900 replace a missing exhaust muffler?

No. It is the removable internal baffle for the compatible stock-style muffler; the muffler body, retaining fastener and exhaust seals are separate.

What should be checked before installing a CB750K muffler baffle?

Inspect the muffler outlet, baffle-retaining hole and fastener threads for rust or damage. Confirm that the baffle seats fully and is securely retained before riding.
