At the independent euro garage that I use, labor to install the headers was $200. I bought the Maxspeed headers that had two bungs per header so they just had to place the O2 sensors in approximately the same location. I get a CEL every other month or so but it takes 30 seconds to clear with an OBDII reader. I bought a couple of sensor extenders that will move the rear sensor out about 3/4 of an inch. I've seen similiar extenders prefabbed on some 996 headers. Thought I'd give it a try as they are only about $10.
