Intake for lots of boost

What is the best intake available for 20+ lbs of boost for cathedral heads that fits under the stock 05/06 hood?

I would add that it needs to be budget friendly like $1000 or so.

Keeping everything under the hood I have is important to me. I don't like huge hoods or things sticking out of them.

Motor Trend's Engine Master's Video Series just did an episode on manifolds for boost. They played with runner length on a FAST 102 at 11 psi. They concluded that longer runner length is still better under boost for the best torque curve. At that kind of boost I might worry about blowing up a plastic manifold although I see a post or two on the Corvette forum stating that they had run 19-20 psi on a FAST 102 without issue.

I believe the burst panel kit sold for the FAST manifold release around 38 psi, so 20 psi should not be an issue.
