Mike, 1 3/4" dia x 36" long primaries (measured to the merge section of the collector), 3" dia collectors, merge into single 4" dia pipe prior to 4" superflow muffler (3.5" modified to 4") and then 4" pipe to outlet in std location on RH side of the car.
The step on the GTS header will most likely help to broaden the torque range I suspect but still a short primary for a 5.0 working in the rpm range that most of us are using.
