Sound wise, the Eisenmann Race System was my favorite even though it was only a section 3 exhaust. However, I still love the RPi GT though because the added power is just so insane. RPi told me that during their dyno testing, they saw momentary gains of up to 39whp. I just wish is was as loud as the Eisenmann!
