I just had x-pype and flowmaster deltas installed behind the cats, but kept the original over axle pipes and resonators. The original pipes appear solid there is a small hole in the outer skin on one muffler. If anyone wants the set they are available. Message me for photos if interested. I wont be able to get photos until Sunday. I'm at the Jersey shore, and not inclined to ship, but may be able to meet within a reasonable disance.
