Mostly it was my lack of welding skill... I bet if I dropped the crossmember it would have fit just fine. I measured the pipes and the spot they traveled, I should have been good by at least an 1". The guy who did my pipes was not allowed to drop the crossmember for insurance reasons. Granted I am really happy with what he did, but still annoyed I departed from my original plan.
The new system I put on was from scratch. The magna flow set is untouched. Now, with that being said, you will need to cut and 'clock' the flanges to match up with your headers. the flanges are off by about 20deg from the stock flange of the XK. Which is weird because why would Chrysler use a different header from the XK to the WK on the same motor? might be an SRT8 thing though.
No issue passing emissions, you will have cats made for federal rules. You may need to program out a DTC depending on how sensitive your O2s are. Sometime with magna flow cats the stupid light comes on, sometimes it does not.
