I am running the TurboWerx headers with the FabSpeed exhaust. Yes, I am catless. This is fine (well, without the environmental concerns) if you flash your DME with the RoW program which removes the catalyst efficiency monitoring.

A lot of guys are running the "Chinese headers," which are, as far as I can tell, essentially copies of the TurboWerx. If you are going to keep the North American DME program I would recommend going with the FabSpeed headers as these keep you legal and will not result in the car throwing codes.
