Keep the replacement scope clear

Inspect the mounting points, connecting tubes and flange pieces on the existing exhaust. If earlier work changed those fittings, establish which stock-type pieces the replacement will require before the motorcycle is dismantled.

Compare the bike and the existing pipes

The product FAQ says this reproduction set has built-in internal baffles that are not designed to be removed or replaced. The separate genuine Honda diffuser is for original HM300 pipes, so do not add it as a routine service part for these reproduction mufflers.

Questions before ordering

Is hardware supplied with the 300-style set?

The listing states that hardware is sold separately. Review the fittings already on the motorcycle and the relevant stock-type mounting products before completing the order, including any flange or connecting components required for the planned replacement.

Are the reproduction mufflers’ internal baffles separately replaceable?

The listing says the baffles are built in and are not designed to be removed or replaced. A separately offered original-HM300 diffuser does not turn this reproduction set into a removable-baffle design.

Is this genuine Honda old stock or a reproduction?

It is a chrome reproduction set. That distinction matters if your restoration requires original Honda components rather than an early-style replacement.

Not sure which part you need?

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