To the OP here's some advice, not worth the money to do everything you want to do on these NA engines. But if you have deep pockets then alright, I will tell you everything you would want to know.
AA Tune
AA Exhaust (New One)
MMW Headers
3 Stage Intake Manifold
Simota V2 Intake or BMW Performance Intake
If you really got deep pockets then you should do a whole complete engine rebuild with all performance everything!

no matter what you do, or how much you spend your not going to ever get 335 type stright line performance out a 325/328/330 so if thats what you want buy something else. or start a lil project car......
aa tune
kn filter, char. del
headers (no cats)

all that will cost you half of what suggested above and will produce 85% of the gains.
