So I just bought a full exhaust, cold air intake, and a Programmer for my 99 328I. The car is stock and I want to add performance. What else can I do to the car to gain performance? Natural asperation is the goal and not spending thousands on each part.

M50 intake manifold swap
+1 and headers, higher differential ratio, software. Maybe a inexpensive NOX kit, 50-75 wet shot.
