2004 Explorer NBX Flowmaster inlet/outlet

[thegator]

Hi, I'm looking to get the Flowmaster 40 series muffler for my 2004 NBX 4.0L V6 and was wondering what the inlet/outlet was. I've looked underneath it (see pictures) and it seems to be center inlet /offset outlet, but when I go to order it from a site, it says offset inlet/ center outlet for my vehicle. Also I want the 2.25 flowmaster right? Thanks!!

This is a picture of the inlet:

Here is one of the outlet:

I think your right they might be quoting on the 4.6??? Some times the books are screwed up...
