Well i no longer live in Virginia

i moved down to Florida for bigger and better things i guess you could say. They really dont bust your chops down here about stuff like that..as long as its not crazy loud. Which is why i was going to go with Apexi exhaust, i was told they made one that isn't too loud unless you WOT.
What kind of header do you have on yours? Did you feel a nice difference with it on?
And i would like to go with exhaust too because the more you open it up the more power your getting
*edit* Also, whenever i get all of this then put it on, would i have to tune the car to get the best out of it? I know i would have to swap computers because 0BD2 computers aren't tunable correct?
