Im getting ready to run the LA barstow toVegas DS event and I am concerned about my exhaust combo not passing the 96DB limit. I have a FMF TI powercore and a mega bomb header. Has anyone ever ran this combo and gotten a DB reading? I know what fmf says it blows but I dont trust it and would rather hear from someone who has actually been tested with this combo on a WR. My bike is an 07 WR450. I would hate to plan everything get there and be turned away. I have the stock spark arrestor that came with the pipe on. Thanks.
