Can a 2000-2003 Header fit in a "2004" GT-S?

Hey guys, but i'm in a tight spot here...anyone care to help me figure out if a 2000-2003 dc sports 4-1 header can fit in my 2004 GT-S....I mean, from what i understand i think there's no difference with any of the engine componenents from the 2000 all the way up to the 2005 model...right?!?!?....am i wrong?....cuz if i am, tell me so...please i beg you.

and if there are any differences, what are they?...i'm just dying to know so i can order my headers already...if you have answers or opinions or in the same situation as i am, please write back...i'm really desperate right now.

Thanks again,
