great pipe but don't expect whisper quiet
FMF products always have top quality fit and finish and this pipe is no different. Fit perfectly and made quite a difference in power. Had to adjust the fuel map to run more rich but i think that is common. It may be slightly quieter than stock but barely. Kinda wierd but with bike sitting there revving it seems on loud side but when riding in dunes, not too bad...
