Go JB4 - you'll get another 30 - 50HP out of it - 10 minute install.
Get K&N filter - maybe another 3 - 5 HP - Dont bother with a conical filter of sorts - waste of money.
Keep it simple - its a low performance 4 banger, not much more you can squeeze out of it. The 530 is NOT meant to be pushed and I would be cautious in doing anything too radical.
ECU retune will get you up to 100 hp - your now at or slightly above a 540 stock yet you have significant risk of breaking something in the motor.
Dont mess with the exhaust unless you want it to sound like a Honda Rice Burner - you wont get anything performance wise and will be laughed at.
If you already have the MPerformance Package then go to RW Carbon they have some really nice upgrades to make the car look bad ass. Throw some 19s or 20s on their too.

There are lots of success stories on 540i & M550i performance mods but I rarely came across any 530i owners' shared opinions on what they've done to their vehicles. So if anyone here has done anything to their 530i to increase performance then I'd love to learn a thing or two from you please.
To break it down, what are your recommendations on the below categories based on your own experience? I'm only after opinions on performance mods but if it comes with improving the looks of the vehicle too then I'm all ears  Thanks guys!
- Chip tuning (Piggy-back, ECU swap, Remapping):
- Air intake (eg. K&N drop in filter, pod filter):
- Exhaust (Whether custom job, full system, muffler delete):
