What I am talking about is (if they ever come up) the tubular header that Ash is talking about for their Z1 Stage 3 BB turbo AT STOCK LOCATION. The pictures of the Stage 3 BB turbo looks like they are mounted at stock location. So far the only aftermarket header for sale at stock location are from Pentroof and Greg Dupree. I never seem the Pentroof manifold for stock location but Chip at GMS had told me he had sold a set of that particular header for stock location. That's why I am wondering is Z1 going to design and make their own new header for the stock location. I hope Ash can answer this question.
