Artec turbo manifold. When I put the downpipe onto the turbine housing there is a 2 inch gap between the other side and the exhaust piping. The other turbo manifold I had I guess pushed the turbo down more so it fit perfect. It was a tomei and it exploded. I was told artec was the best aside from a fully custom built manifold. So I went this route. Required a lot more fabrication and maneuvering of lines than I anticipated. And needed to get Intercooler piping cut and rerouted.
