Just payed for this today:
It is the SVT Focus header with a custom exension to match up to the ZX3 flex-pipe and O2 bungs welded into the primaries. Only paid $240, as opposed to $340+ for aftermarket units. Should be interesting to see what kind of power increases this will produce. It also eliminates the need for an EGR, so I have to get a custom chip burned to ditch the check engine light for the lack of an EGR and a cat.
