Like Jeff says...
Needswings or TVT Design.
TVT Design has a dyno of their intake, as yet Needswings do not (they have a dyno for an earlier intake of theirs).
I believe TVT's is cheaper, and it is probably very easy to adapt it to the Needswings routing (which I prefer).
It's all been discussed here, at great length.
I would be willing to bet that for hp per dollar the TVT intake is better value for money.
