I've heard the RPI 550 axle back exhaust in person and can assure you it is not 'too loud', when driving under normal conditions. From the interior of the car, windows rolled up, you can hear the slight rumble of the exhaust. but when the car is at WOT, the sound is exhilarating! 
All the exhausts you mentioned are going to sound similar when driving aggressively. The RPi will produce the most power and I highly recommend going with it over the other two.
As Gene mentioned, there is a group buy currently going on. please add your name to the list if you would like to take advantage of the group discount.

I made a mistake, i was reading the torque instead of the hp.
The actual numbers are 12 -15 hp over the magnaflow

This is why folks love the RPI exhaust. A mean sound and more power. I wish I could ditch my stock exhaust for one but with a leased car and no place to store a stock exhaust (apartment life in NYC), it ain't happening.

My Ride: SOLD...Jet Black 2008 550i M Sport with SAT, black interior. RPI exhaust and air scoop, 35% huper optik tint all around, CF roundels, flat black kidneys, Springfield Armory XD-40 jet black in glove box, charcoal filter removed.
Hey vcbimmer, if you get one and have it installed, let me know where and how much. You're from the philly area, right? I'm from Harrisburg, currently deployed to Iraq, but want to order one of these and have it put on when i get back in September.
Hell, maybe we can just get together and put them both on once i get back. Shouldn't be that hard, right?

I hope that the both of you can attend the meet that I am going to out together for late September/early October to Pa State Route 125 -- Eastern Pa's ultimate twisty road. It is about halfway between Harrisburg and Allentown. Then we can hear the RPI exhausts roaring in unisom.
Sounds like a blast - let me know when it will be and i will try to be there. don't know if I'll have time to get the exhaust in by then, but i'll try.
