The heads on the vhr motor are not symmetrical which had the manifold in a not so ideal position. With a few design tweaks gtm was able to correct the way the manifold sat and now we may have the possibility to retain the stock cross member *fingers crossed*. now that the manifold is situated we are working on the reproducible fuel rails to allow you guys the chance to get this upgrade. Before we had one sized fuel rail for the right and a different size for the left. With the new manifold version gtm has simplified the design to allow the same size on both sides!!! keep your eyes and ears up for the next week or so
