I have a GT2 ordered, due to arrive Wednesday and will probably go on either Thursday or Friday. I'm already thinking of getting an x-pipe. Throwing on test pipes changes the high rpm tone a bit and makes it slightly raspy.
Anybody have any ideas of what x-pipe would keep the tone without rasp and just increase the volume? I'm leaning towards a HFC and resonator set up.

Edit: What if I just remove the secondary cats from the stock pipe?
