Mkodama, we worked hard on this project to bring HPF and the N54 community a new product that was never available. What you're missing is the fact that we pulled this off and HPF can now offer this to there customers. You're picking at a single manifold that was made during r&d where changes were constantly being made. The big picture is HPF is working towards a fantastic kit for the N54 and we are always pushing to produce perfect manifolds.
That being said, it was a pleasure to work with HPF on this project. Fitted with the turbo and other parts as well as a tune, the manifold will definitely exceed HPF and HPF customers expectations.
