What I would do is use a blockoffplate for the EGR, grind off the EGR port on the CAT and weld in a bung there for the wideband. I don't have a pic of the stock cat here but that to me is the easiest. I think in the header is real tight to put a bung in to get accurate readings. you want it slightly down from the connector to ensure your reading the a/f from all cylinders.
Also FYI: SVT header will not work well at the bottom flange, due to the collector design down there.
Thanks guys ... and Jamie it's the Zetec header, otherwise I think I'd have more options ... hadn't thought of blocking off the EGR because the Jackson racing has the fittings for that ... might also work to lower IAT's ... I can't picture how much further down that would be though
