Default Header compatibility

I have a 2000 Gt stick and I am going to be getting a 2001 Cobra 4v motor for it very soon. I was wondering what type of headers i would need for this motor. Will the 99-04 GT headers work or do i need to get a different year/make. All helpful input is appreciated.

Im 90% sure you will need headers for a 4V as the heads are different on a Cobra engine.

4v headers are different than 2v, 2v have circular runners, 4v are oval.

edit: btw, where at in NJ you at?

I am from South Plainfield however i am now currently in North Dakota...

As for the exhaust. so if i were to order headers for say an 03/04 cobra they would work on this 01 motor? just askin cuz the ones i want dont have any selection for just 01 cobra..
