Original pipes?

[Andrew Eidsness]

My Dad owned a 1976 CB750, I'm helping my Mom to sell it after he passed away. Our first step is trying to figure out a reasonable price. From what I understand a big factor is whether it has original pipes.

Is there any advice on how to figure this out? I have pictures, which I've compared with images online. To my eye they seem the same, but I'm trying to figure out how to tell for sure.

Otherwise, I would rate the bike in fair condition. It starts right away and runs, but there is some signs of surface rust on the spokes, the back license plate has a wire to hold it on, etc.

The Honda HM341 exhaust pipes are a factory-spec exhaust system for the Honda CB750 (K5), produced for model years 1972–1976

You can find the numbers stamped on the mufflers

Thanks! I don't see that in the photo that I have, but perhaps it is the wrong angle. I'll check when I'm there later today.

UPDATE: I checked when I was there, but didn't see any type of stamp on them. Thanks for the help solving this.
