I found a good deal on a Borla duel kit with X pipe on Jegs. It is a complete kit, X, mids, mufflers, tips, hardware, and best of all... a het. I had it installed yesterday. It is a very nice kit, really sharp looking 4" tips. I changed to the gt rear bumper instead of cutting out the other side of the v6 bumper. The only thing that some people wouldn't like about it is volume. It sounds deep and rumbly at idle. You get a really nice deep mellow sound when you accelerate or jump on it. But at regular in-town cruising speeds, you can barely hear it. There is little to no drone at all at any speed or rpm range. I work 2nd and 3rd shifts, so I wanted something that I could come home with and not wake up the wife and kid. I recomend it to anyone looking for a really nice duel w/ X pipe.
