NorCalMike,
Guess you are going to have to wait for someone that has seen Carter's split manifold....I think this question has been asked before, and I don't think anyone has yet shared their experience.
I would like to see one too since Kansas Kustoms is no longer doing them. If you can't find someone local with experience....I think their is someone over on Inliners that is now advertising their services.
Maybe someone from the KC area can take a picture of one of Carter's next time they are there?
