The magic 8-ball says your answer is: "Pickles"

 

if you plan on using the stock gsr manifold you will have to have your fuel lines lenghthend so you air intake will clear. save yourself some trouble and go with an aftermarket manifold. Also if you stay obd0 those secondaries wont be functional in that stock gsr manifold.
