Its kind of like what happened with the MREV2 that is used on the prior 350Z. A modified stock manifold was used on a newer generation engine and it makes really great gains.
Many companies have tried to design plenum modifications for the 350Z. Anything to squeez out a little more performance... And still nothing comes close (in terms of dyno performance) to the Motordyne MREV2 with the 5/16" plenum spacer.
What I can say with certainty is the Motordyne M370 is the highest value and best performing manifold available for the VHR engine. And it makes appreciable gains.
