We have not had this header yet on our car but are looking to do so VERY soon, and we can provide more information then, but I see a mechanical fix being needed at this time to stop a possible CEL.
You cannot remove emissions control devices before the sensors and not expect a CEL, it will happen.
This isn't a mod for everyone. This item is perfect for someone building a N/A track car or someone that is okay with CEL issues/fixes, along with taking full responsibility for the emissions side of things.
A header with a CAT will more than likely be developed by other manufactures. It will take a lot longer though for those to appear on the market as R&D is much more involved and costs would be close to double what you see here on this guy. Also HP/TQ gains will not be as large with a restrictive CAT in the header.
Cliff Notes:
Worried about warranty, cops, and emissions laws? Keep the stock header in place.

From what I hear, the stock header isn't a bad one to begin with, right?
