I don't think that headers or lack of cats will add much noise. The biggest factor will be the mufflers you choose (and/or the resonator, too, if used).

When does an officer listen to the car to determine if it is too loud? Is it after they've heard you on the street and they thought it was too loud? If yes then I think you should also be concerned about WOT sound.

Personally, I really like the cut-out option. It's the best of both worlds. I'm not surprised Gunny is happy with his. But I do agree it adds complexity.
