....We thought we got lucky when we test fitted a set of BBK long-tube headers designed for the '05 and up Mustang. The driver side header, shown here, fit like it was designed for the swap, but when we tried to bolt up the passenger side header our luck ran out. Several dimensions just didn't work in our favor. We're still trying a few ready-made options, but we might be heading down the path of custom-made headers. Stay tuned for more.
