Hooker makes all kinds of black seramic pipes. Called Darksides. i just ordered a set of the Fourbidden Darkside for my '07 Train, and a power commander with the O2 eliminators
Joker Machine makes a couple of different sets of black pipes. Really nice pipes. I have one of the chrome sets for my 04. You can get them on EBay for less then manufacturer, but are new in the box.
If you're not concerned about the cost, pick any pipe you like and just have 'em Jet Coated. Put your own 02 sensor in if it doesn't come with one. It isn't anything but a bung welded to the pipe. That way, you'll have the option of any pipe out there. I had a set of Arlen Ness Ultimate Radius pipes on mine until this last rebuild. I sandblasted them, high temp painted them, and wrapped them in heat wrap. Looked good. I just didn't like the shape of the pipes. Good luck.
