Thanks for the info.
I have seen on the turbo forums that guy's use these manifolds. They turn them around so they face forwards and then run a turbo setup. Can I still buy these larger manifolds brand new?
If you mean the 1 7/8" outlet manifolds, I do believe they sell them new. But why would you buy a new one when you can get a seasoned one from a salvage yard?? I prefer a seasoned manifold over a new one because a manifold that's been tested over thousands of miles is less likely to crack.
