QR Code Link to This Post Really nice set of 4-4 drag pipe exhaust for a SOHC CB750. I don't believe they're MAC pipes, but they are very similar. This exhaust is designed to use the '69-'76 spigots, but you can use them on a '77/'78 motor by installing the earlier spigots (I have some available at extra cost if need be). A very little rust in the welds of the mounts, some dulling on the chrome, but overall an easy 8.5/10. They had baffles (long gone) and as such there's a small hole near the end of each pipe where the baffles were bolted in. Can't be seen when mounted, doesn't really affect anything. $175, can meet in the Frederick/Hagerstown/Monrovia area for pickup. See my other ads for more CB750 parts.
