Exhaust manifold is the bit that connects the head to the turbo....
Re: dumps, the xforce ones i have are different. You have to hold them together to notice because they look so similar, but one is bent around more tightly than the other, and the wastegate pipe joins the main pipe in a slightly different location. There would be about and inch difference in the location of the front pipe flange, so yeah its looks like you have them on backwards.
You're doing better than me - i still cant get the effing front manifold off. I'm going to try moving the power steering pump - is that what you did?
