I'm not sure if this is the correct forum to place this, but I couldn't find a parts specific forum at SOHC. I have a 76 CB 550-4 K3 that I am in the process of putting back together and looking to buy a 4-1 exhaust. Ideally I would like a 70's era Kerker thats someone would like to sell. It doesn't have to be in pristine condition since I plan to wrap the header. I am also open to other pipes if you have somthing sitting that is in decent shape. Lastly, I can't seem to find a "new" option, other than the MAC exhaust. Is there a Hooker, Jardine or some other new equip 4-1 option ? I've seen a few a 2-1 options on-line that are beautiful but more money than I can justify spending. Any insite would be appreciated.
