Those manifolds from SSI looks very, very similar to those from China and ebay. If they are made by SSI then I wanna apologise that i said they are made in China. The thing is that they looks very, very simlar and when I have ordered my manifold from China the man who was e-mailing with me told me that they can engrave any logo I want on it or they can leave it like it is.
You can have them as well from USA, Australia, Malta, Poland
