I have been looking for a 550i for a while, decided to drive a E92 coupe as I had always loved the styling sound (plus the ability to extract a heap more HP for next to nix is attractive also) and after driving a manual I am definately on a lookout for a neat manual E92!
Yes thats $550 fitted, a dyno is available at Advan performance for ~$70 I believe.

The downpipe part of the exhaust proves to add around 20-30kw at the wheels

The midpipes and rear muffler will maybe give 5-10kw if that...

So, conservatively, a 'full' turbo back exhaust would give ~25-35kw... still pretty good gains and doing downpipes is still good bang for buck.

The CAI can add 5-10kw and priced from as low as $139.

or the nicer looking, but more expensive AFE

FMIC only adds 5-10kw... do it for cooling purposes, not if you want to chase power.
