the V1 + extra piping to place the intakes by the stock intercooler location... so really it's the same setup. Hasn't it been proven anyways that a single intake design will flow enough for 500 ish HP anyways? I would personally stick with doolz. There's the dyno's behind it to prove the gain and you don't have to risk the low speed drivability issues.
