Used this on a 2013 F-150 with 5.0 V8. This went on my 1996 F150 with 351W as part of a 3 inch mandrel cat back upgrade.
What size are those in and outlet ? Three in and three outtt Fit in a nissan 350z 2007 It has to be welded, so naturally It will fit in whatever you put it in. I’m guessing your asking about size I don’t see any reason it wouldn’t fit a 350z
