I have an S4 TII, and I just bought a bunch of random parts a guy was offloading. In that parts was a XS Power turbo manifold. Does anyone have any experience with these, are they junk? Here is the link to their website.

its a copy of the HKS log, but made with questionable build quality.
it should work just fine, it just might not last as long as the HKS cast iron

 

guess ill run it until it breaks or I impulse buy a better manifold.
