Is the header flange the same bolt pattern as the 03-04 Cobra, Talking with Bassani and We don't know if they use the same flange pattern. What headers are you racers using?
well, that, plus headers are hardly worth the trouble they cause.
cast iron exhaust manifolds are simple as an anvil and dead-nuts reliable.
tubular headers, not so much. unless you like tickticktickticktick leaks at the flanges, pinholes, and flat spots. that plus the o2 sensor usually ends up too far downstream to do its job properly. It doesn't belong in the collector.

Hello,
I am looking in doing the same thing, the 00R, ford gt and the 07/08 shelby 5.4's have a different exhaust bolt pattern than the standard 4v heads...BBK will sell you flanges for the 07-08 shelby 5.4, but they are not cheap...I am going to have mine cut on a water jet using exhaust manifold gaskets as a template...
If I was able to get a mid length header from Bassani, is there any interest, I may have take him my car. He made a set for the 03 Cobra that are step, 1 3/4 to 1 7/8 to 3" collector, He says on a 03 to have made 20rwhp.
