I still have a prettty much stock 06 gt with stock headers, pypes o/r h and flowmaster mufflers. I want the kooks long tube and catted x pipe system but am curious about the sound. Will it be louder than my current setup and will it sound good with these mufflers. Im planning on a kb twin screw soon.... so what size is recommended. I also have an eibach pro kit and have heard about ground clearance issues.......thanks

I have that exact setup and with the long tubes the car is much louderand deeper. I had the pypes violators and then switched to flows which I currently have now. I love the sound. The 1 5/8 system is plently for a car making up to 700hp. Hope this helps.
