If you want sound and power increase go headers. If you just want more power do the intake manifold. Headers would be the cheaper option as well, assuming you're looking at new parts for either options.
By software do you mean tuning? This car is my daily driver. She already makes a great deep sound stock but it would nice if could hear it a little more from inside Headers sound like the way to go for now until I can invest in an IM.

gixracer i'm picking up what your laying down! My ultimate goal would be to set her up like that.

As far as tuning what do you guys use to do that? I bought an OBD connector and some sh*t software off Amazon once and didn't really get anywhere with it. If you guys know of some product that works great please make me aware!
