Mods for spec-v

[lude fan]

This week i'm gonna buy a 2004 Sentra Ser Spec-V, and i'm planning to modify it soon, first i'll buy i/h/e, after some research, i'll submit you my choice:

Aem Intake
HotShot Headers
Megan Racing downpipe
Apexi ws2 cat-back

I would like to know if this is the best setup i could buy, if my priority is:
1-Performance
2-Quality
3-Sound
So, to resume i want to be the fast, quiet, stay street legal, and it is a broken/repair, so i dont want to buy stuff that can hurt my car or engine reliability, cuz i dont have any warranty.

Thx for yur help

Actually, i've heard air flow mods aren't really the way to go as far as speed. I know you want it to sound good, but if you want more bang for you buck, go with a performance fly wheel and some better pulleys... this is just what i've been told. I'm looking into modding mine, too. However, the header is a definite plus. This is so because you have a second cat right on your stock manifold. Dyno tested, a hot shot header can give you about 15 hp at the wheels. Hot shot headers are supposed to be the best. At specplace.com they are on sale right now for about 300 dollars, which isn't bad. I'm looking into getting one for my 03 spec v. I'm kind of in the same place you are, though. I want my car to sound good, but for the price of exhaust and the gain you get from it... it almost makes it more of an appearance thing than anything else.
