RE: stock exhaust size??
Just for a third opinion, I went to the garage and measured the stock exhaust that was recently taken off my 04 4.7 when I put the cat back dual exhaust on. It is 2.5". The pipes after the muffler on the dual exhaust are 2.25. They did that so it wouldn't affect something on the low end ?
