    I'm searching ebay for headers for the 04 GTP and so far everything is coming up as '97-'03, and only fit the monte carlos and regals in '04 and up. What changed in '04 for the GTP? I mean, I know it's a series III engine with the gen 5 M90, but so are the monte and regal I thought? Why would '03 headers not fit an '04? Is it just a matter of the crossover tube, or are there other issues? If it's just the crossover tube, I'm gonna order a set and just modify the crossover.....

    nothing changed, buy the headers for a 97-03, they fit.

    98 Buick Regal GS, F body brakes, Caddy STS wheels, tinted tails L36 bottom end, lightly ported heads, 1.95 roller rockers, headers, gen 5 N* 3.0 pulley, FSIC, 42 lb injectors, a BrandonHall rebuilt trans, DHP tuned and AEM water/Meth injection https://goo.gl/gpV5kW
