Magnaflow catted X or Prochamber???

[SVTdubs]

I have a magnaflow catback, should I get the magnaflow x pipe with high flow cats or the mac, prochamber for my 03? Any opinions or power numbers with these options???

I heard the prochamber wont fit our 03's?? But you cant go wrong with a bassani or magnaflow x pipe with your catback!!
