Hi all. I have for sale a 4-2-1 header I bought used not too long ago. These are MAC Racers Choice exhaust for SOHC Honda CB750. I don't have the muffler for this because I was going to build a custom muffler setup. I just dont have the time or space to really get to this so I'm putting these up for sale. No these do not fit DOHC. Asking $120 shipped obo.
