FWIW, I only gained ~ 12 rwhp on my '01 Cobra after installing JBA 1 3/4 shorty headers.
However, I gained almost 40 rwhp @ 6800 rpm, and had more power just about everywhere else in the rpm range as well.
Well-worth the $$$ & PIA install if you ask me...
Additionally, when doing other mods the exhaust manifolds WILL become a bottleneck sooner or later - that's a proven fact.

And just how often is some one going to drive at 6800 rpm, esp for the average joe blow street driver? Is it really really worth it? Can you justifie the time and money to adjust your driving to always drive at 6800 rpm? and that is if your engine will stay together all the time you take it that far all the time.
