They are indeed - with the exception of the first step - stage 1 software which give s healthy lift in performance - from then on with hardware and software its expensive.

are t5 cams stock oem saab cams?
On the old 9000, but I wouldn't bother if you're still using the GT17, that can't really move enough air.

EDIT
T5 refers to the Trionic 5 engine management that came on the 9000. Your car is a T7, or Trionic 7, which has better flowing heads so it got smaller cams.
