I have the Eisenmann Sport and it is definitely lounder than the full RPI system. The RPI sounds good...It has a higher pitch sound with a little lower db rating than the Eisenmann. The RPI does maintain the gurgles and pops that we have all come to love with the M5. If you are looking for a more stealthy understated sound the RPI is a good way to go. The tips look great and do not protrude too far out from the rear bumper. After hearing both, I am happy I went with the Eisenmann, but the RPI solution is good IMHO.
