99 and 01 Headers don't have the fittings at the front of the headers for the metal tube to connect to, which I believe goes to your air pump. The only fitting my 01 has is on the driverside header that the EGR screws into and goes up to the intake. When I compared the actual headers to my brothers 97 longtubes on his Cobra engine they looked like other than the fittings being different that they would bolt right up. Hope this helps.
Thanks for the help. I believe the ports are the same as +99, Hooker headers are universal. Arent they oval shaped. I will be installin the headers in about a month, I need a dependable clutch in their first!
