I currently have a wr450 with a fmf factory 4 pipe and powerbomb header. It is LOUD. I put the PMB insert into it and it got a lot more quiet, but still not the stealthy off-road weapon that I would prefer. Where in SoCal could I go to check the noise level? I'd like to know. I am considering switching to the FMF Q2. My goal is to be as quiet as I can be and still have very good performance. Looking for a balance here... Does anyone know of where I could find the db levels on the various pipes? Does anyone have any experience with the Q2?
