This is how GM Motorsport went with their "Project Redback" VE SS sedan, on their Mainline dyno..
Dyno Results:
Stock with Ripshift
217 rwkw
Ripshift, Tune & GMM Airbox
246 rwkw
Ripshift, GMM Custom Cold Air Intake & GMM Custom
Maf Tune
252 rwkw
Ripshift,
Maf-Tune, GMM OTRCAI, Di Fillippo Exhaust
283 rwkw
Ripshift,
Maf-Tune, GMM Custom Camshaft, GMM OTRCAI, Di Fillippo Exhaust
352 rwkw
If I recall, even the LS1's used to gain a bit with a tune only, even with the stock exhaust...but of course if you want to make max power, an exhaust is probably the first thing you'd do
