as a beginner

i know nothing about aftermarket mods. i know what works but not what's best for the car. having just got the 04 gt v6 where should i go to find the best way to add hp? i just don't see a normal garage taking care of stuff like this.

exhaust- borla greddy tigerlilly mussa apexi
cai- injen kore aem
headers
cams
super charger- alpine ripp-mods h.a.r.d. other companies working on them
turbos- greddy apexi race-real plus custom

if youre really serious of gaing hp and if youre gonna be at teh track or such...
weight reduction: taking out uneeded stuff in teh car
carbon fiber hood
light weight wheels
racing slicks

if you have any questions.. pos t em up ill be glad to help

would it be safe for me to go online and just order the stuff or is that asking for trouble? i don't have any friends into the scene so i don't have anyone to ask what works best. all i have is import tuner... i'm so sad.

wellif youre ordering online.. make sure its awell known company....
all the companies i named up there are good and respectable companies... except kore.. even tho i think they are outa bussiness... due to obvious reasons

so outside of the little details, is there much difference between companies. meaning would one company make the same part to do more than another company or does it just come down to personal pref.?

uhh some is personal preference... liek sound of teh exhausts...
some its hp gains.... liek dif cai intakes...
others its reliability of teh company...
warranties
