moutning wideband
i think the pacesetter headers are aluminum and i heard that you gotta get a special weld on aluminum.
If you wanted to be really slick, you could set it up to work as a narrowband and wideband, then put it in a factory hole and delete one of the factory narrowbands. You can read up on it in the PCM section.
The Pacesetters are mild steel, just ceramic coated. Buff off the ceramic coat around the weld area if you're going to weld the bung on the primary.
