I was wondering if there were any 545ers out there who have the Dinan Exhaust. I am going to do the Dinan Intake system, Throttle Body, and Stage 3 Software, but I am not sure if I want to do the exhaust. I like a good exhaust sound, but in this car I really want to make sure I don't have any boominess, Drone, etc at cruise. Ideally, I want the car to make a statement under throttle, but have no sound issues inside under normal driving conditions.

Search for "Dinan exhaust" under "Parts, Accessories and Mods", you'll find more answers than you'll ever need.
BTW, good choice on the intake, TB and stage3 SW. You'll love it

I have a 2004 545i SMG Sport, I have the Dinan exhaust and it's perfect, it makes a clear statement under throttle as you asked about. But when cruising, sometimes I forget that it's even there until I downshift. It's a perfect balance, when I'm sneaking in the house late, I just go easy on the throttle and no one will hear me pull up!

Do you know if I lose much in performance if I do the intake, TB, and Stage3, but keep stock exhaust rather than Dinan?

The RPI exhaust is awesome, hands down. They produce products that only produce gains, hence why they refuse to make a quad exhaust system. The RPi exhaust has a nice deep growl and no drone. There is a little hum on the highway but you won't notice it unless you are specifically listening for it. All in all I'm more than satisfied. I remember a post about a member wondering if it would be too loud since his car is a family hauler. He ended up buying it and said it didn't bother anyone at all.
