I have RPi GT and love it! The Eisenmann is louder, but with RPi you can build up more sound if it's not loud enough to begin with by adding and x-pipe and/or high flow cats. So if the Eisenmann is too loud up front, you're kind of s.o.l.
Coming from someone with the Rpi GT exhaust, the sound is intoxicating.
