With all of these power gains with complete exhaust systems, I'm wondering where the restrictions are in the stock setup.

I mean, I get it that the stock exhaust manifold will not flow as well as headers and the stock mufflers seem to be very restrictive. But isn't everything else in the middle pretty good?

I'm gonna wait for the GMPP shorty headers and axle-back to be dyno'd before making my decision. I'd like to keep my warranty.
