|0h5iveZX4ST||What are your guys opinions on the OBX header and flex pipe? Edit: for a 2.3 duratec zx4 ST|

I found an old, unused F2 header on ebay almost 4 years ago now for dirt cheap. I painted it, wrapped it, and have been running it ever since. The wrap is starting to fall apart, and I had to replace the flex pipe with a custom made piece I had a local exhaust shop make earlier this year, it completely gave out and was leaking everywhere.
The F2 got a bad name for fitment issues around the firewall and more specifically the alternator, also famously known for crap flex pipes. However, functionally it certainly works better than the factory manifold and most versions have at least two, if not three o2 bungs.
If you already have it on your car, leave it alone until you run out of other stuff to change out... but you might want to check out the flex pipe, make sure its not leaking. The flex part leaks or sometimes the flange will warp making it impossible to seal with your midpipe.

The headers were fine from what i have read, probably on par with the OBX. I dont remember if they were coated or not, if not you'd want to wrap it (adds more cost.)
Bruce suggest FSWerks as they make quality parts, this one is essentially clone of the Cosworth header and it is coated, so no wrapping needed. I want to say the FSwerks/Cosworth has slightly larger primaries too. They also have good support for the focus and have been in business for a while now.
Only problem you'd face is no support. Not sure if other brand flex pipes would mount to it, those typically are the parts that wear out the most. If you can find an F2 in good shape and the price is right, I'd say go for it. Just know what the OBX prices are for comparisons

|svtfiend||Hate to tell you Bruce, but you're wrong. It's an F2. Based purely on the location of the o2 bungs. I've never seen an obx with a bung there. The F2 had 3 bungs on one version, same one I have|
