yeah some of the older 4 cyl mustangs and rangers came with a factory, tube, shorty header. There are a few full length headers out there. Shoenfeld and pace setter. Both are NOT smog legal and take some minor fab/modifications to make work. The pace setter is a very thin pos. The shoenfeld is nice, but like I say takes some work to fit right. Thier both actually made for pintos, but will work in a ranger. Its kind of alot of work for minimal gains, but I had this engine in a race truck so every bit helped.
