Topic: 77-78 CB750A NOS HM 393 exhaust value?

[Garage_guy_chris]

Hi guys. On the weekend I came across a set of NOS BNIB CB750A HM393 exhausts. After google-fu it appears they are for 77-78 CB750A. The price was right so i picked them up on a whim. I checked out the part numbers but not much info is coming up? I found a thread on here from 2011 indicating at that time they were selling for about $800 on Ebay? Any ideas what a fair asking price would be these days? They might end up on my 74 750K project or i may sell them to help finance some HM 300's or 341's

Hello.
The diameter of the headers are smaller on the CB750A!
The oilpan on the CB750A is lower than the other CB750 SOHC!
Sell your pipes and buy other pipes to your bike.
I have bought new CB750A pipes on Ebay to 800$/set
and used very good used pipes to 200$/set.
The Hondamatic pipes are very rare, especially good ones

It is really going to depend on whom is looking for them at the exact moment.  If they are brand new I would expect you could get anywhere from $300-$500 but again it's a matter of whom is looking for them at the time.  Your best bet is to post a pic and see who responds.  Or put them on Ebay with a reserve you can live with and be ready for a wait until the right buyer comes along.  Your waiting for the one person who wants the bike to be completely restored to stock. Most of the Hondamatics that are "stock" seem to be bought with the exhaust already in good shape.  The problem is that the bikes don't fetch high prices comparatively so it's hard to justify paying so much for the stock exhaust.
