I think there is 10-20 HP left somewhere in the exhaust system, whether it is through tuned headers/no cats or both. The MAF is supposed to compensat for any additional air pulled through with additional fuel, but only to a point and since this is a high compression SC car, my concern is a lean WOT condition. Short of an airfilter, I would be cautious with any additional mods that don't include some type of additional fueling/tuning.
I think the exhuast is capable to flow pretty well for the 800 HP it makes (minus the 60-80 for the supercharger drag).
