IMO the reason is since there was no way to tune the exhaust side there was only so much you could intake. What was available to increase on the intake side without overwhelming the exhaust side is achievable with the factory intake manifold. Same reason why there is very little choice in cams, valves, PnP's, retainers, springs, various valve jobs. No real reason to make something if you cant tune it. Give it another year or so and see what happens with the VVEL unlock.

Now was there any flow testing dont on either of these manifolds vs the stock one? ONly reason why I ask is due to everything I have seen on here so far is that neither manifold really produces any significant results. Is that because it flows the same rate or because the tuning hadnt caught up with the design?
