I would also be curious as to how much difference there is between the OEM Gen 4 exhaust that was used, and the OEM Gen 5 exhaust.
According to Dick Winkles they gained between 5 to 10 HP from exhaust improvements, plus cam, plus intake, plus more aggressive tuning to get to the G5's 640 HP.. From my understanding the exhaust manifolds are identical, just manufactured by a different vendor..
