That's nice.
Do independnet dynos confirm that? Are they using SAE correction (conservative) or STD correction (overcompensates for NA).
Anyway, with no baseline run, you cannot determine anything about the % improvement from their exhaust, so a value of 302 is meaningless.
I'm amassing a database of 370Z and G37 bone stock and modified dynos, so I know what I'm talking about. Moreover, I am making reference to SAE corrected values, not happy overinflated STD ones or randomly high/low uncorrected estimates.
I'm a data driven, "bang-for-the-buck" kind of guy, so those are the recommendations I make to anyone who cares to listen.
Of course, people are free to base their decisions on whatever criteria they want and people can spend their money however they choose.
I'm not selling anything, so it's no biggy to me -- I'm just looking out for other car guys who may not have the wherewithal to consider all these factors before laying down their hard earned cash for stuff that may or may not live up to expectations.
P.S.
273 +/- 5 = as high as 278, 1 whp less than you noted. In other words, that is close to the range I have found, albeit on the higher side. I have also seen multiple baselines closer to 268; they tend to dyno higher after accumulating 2-5K on the motor, most likley due to continued wear-in.
