Josh I love scorpion! I did the 4.8 exhaust because of price (my friend was parting out), and it's not much louder than stock. I may do an Xpipe later on. All the E53 exhausts are so expensive. I'd probably do Eisenmann if I had the $$.

For the $1200 they charge the Billy Boat is a nice system, I just don't like their tips (oval single tips but not as wide as iS tips)

Make sense? Remus is quiet like stock, but in my opinion find a used 4.8iS axle back and install Xpipe for perfect sound.
