When I had an E90 325i 6spd I got owned by a stock 2006 Civic SI and 2009 V6 Camry. After that, I realized there is no hope for performance gains on this car. At least it looked damn good and felt great on the backroads (had sport package). So imo, focus on cosmetic and handling modifications. Dont mess with any tunes, intakes, or exhausts unless you want to pay money for sound.
