hi! i am used to working and tuning on honda's mainly and anything pacesetter makes for imports is total junk... but now i bought a gto and i am considering buying their uncoated longtubes. i was planning on keeping the stock midpipes and welding the stock cats and keeping the behind the cat flanges to considering their 3". (mod list in my sig) I would like to keep the stock cats to keep the noise down.

do these pacesetter headers make power?? also can i tune them to run awesome with the diablo tuner?? i will just header wrap the longtubes anyway, no use in buying the chrome ones. all the other brands are just way way to overpriced. I intend to put a bigger T/B, cam, and intake mani on the car in the future and that's about it for performance mods. thanks for any input in advance!!!!
