My brother bought these for me thinking that they would fit my car, an 07 GT. They are obviously not for the 4.6 3v but I can't really tell what they are for. Any help would really help me out as I am going to try and sell them.

 

not 100% but they look just like my bbks for foxbody.

 

i kinda thought the collectors looked like the ones on my '88 but the bolt pattern for the heads is different. I looked at a couple different places selling 4.6 2v headers but they have a different flange on the collector on the passenger side. the extra little threaded tube for what I assume is for an o2 sensor sticking off of the passenger side of the ones I have is confusing me also, in the pics I have seen for the 4.6 2v motors that tube is on the driver side. so at this point I am starting to think they are for a 4.6 2v but not a mustang, but I dont know.
