2009 BMW 128i
Looking to mod my BMW e82 with and N52 engine. I wanted to fully mod this car and add as much horsepower as possible. Was thinking I would start with headers, exhaust, and intake but not sure what the best of each is. Any suggestions?

Headers are not as good on these as a M54 for example.

Best mods / price / performance for these cars....

3 Stage intake (find one used)
Secondary cat delete (5-10hp instantly)
Remove charcoal filter and get high flow filter / elbow (pulls better and revs freely)
Tune for 330i (Free if you can do it)

All of this will give you the best bang for your buck.
