If the former (the cats), easy to address with an N55 or Berk Tech midpipe.

Neil, no, I'm not referring to the cats. What I was trying to describe earlier is what appears to be a restriction in the stock exhaust pipe immediately downstream from the flange where the cat-back portion connects to the secondary cat and resonator section. If you look at the diagram of the stock exhaust that Nate posted on the other thread, it's just past the dashed line that separates the portions of the system. It's hard to see from the diagram, but it is noticeable when you look at the actual pipe.
