exhaust end cap

i picked up the fmf factory 4 about a month ago and like the performance. besides melting pants on unshielded header pipe, the only thing i would like to try changing is the volume. i was thinking of trying the quiter end cap. has anyone had experience with these.. is there a loss in power?
