Just for the proper function of the unit, it might be a little too far downstream at that location. Additionally, you may want to keep the res to quiet the headers, then later on have the option to delete or upgrade to a Magnaflow.

For my daughters Zetec, I added the 4-1 headers and placed a new 'bullet' cat right after the headers. Kept the stock res which I plan to replace with a Magnaflow or similar in the next week or two.

Must be that jumbly-wumbly thing happening again.
