I don’t have any data other than “looking X guessing”. I would bet the stock LS7 Camaro Z/28 Tri Y headers will make more power. The GM Powertrain team did a lot of work on those Z/28
Manifolds to get over 505 HP stock.
I have made over 800 HP with the Holley exhaust manifolds on a blower motors.
Both are good. The Holley’s fit the “look” of the engine bay better.
