Torqstorm.. let's see how it does

So I've been thinking. I know mathematically a dual 3" exhaust can support 680-700hp NA (for a zero loss system)... Does this same math still apply to exhaust size when in a boosted application? Would a 3" straight through style exhaust still only support the 680ish hp or can it support more? Obviously with turbo's I've seen people make 1,000hp through smaller exhaust, but Supercharger? I would think the math still applies to the supercharged engine.

I've been thinking about building a new exhaust to fit my TTi Headers, since they have 3.5" collectors I figure it wouldn't hurt to build an exhaust that is 3.5" throughout.
