Is your X-pipe installed where the twin resonators were or where the 3rd resonator(box) was?

Does it make a difference between location? I read on here that H-pipe give it a muscle sound. Thanks again.
Their is absolutely no interior noise at any speed and no one would assume this isn't how the car was suppose to sound. Overall - very clean and OEM sound, maybe 10-15% louder than the whisper quite stock setup but at full throttle from the outside it sounds a lot more exotic and high-revving. My x-pipe was installed where the front two resonators were and for better flow the shop used a step up 3" x-pipe(meaning it steps to 3" then back down to 2.25").

H-pipes generally do make deeper sound but aren't quite as good for performance, no one that I have seen has put one on a 6er.
