4.6 High-flow JBA Shorty Headers – These headers feature a modified TR-Y configuration for improved scavenging and static airflow. A direct replacement for production headers. JBA reports that it fits 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003 and 2004 Mustang Cobras. I know that they will not fit GT’s because the GT’s have smaller 1 ½ inch square ports and these have larger 1 5/8 inch oval ports. Please do your own research as I can only vouch for 2003 and 2004 cobras. The part number is 714-1625S-7JT and they retail for $699.95. Thanks… Not available for one week as they are being shipped from Montana.
