i don't know about a the muzzy exhaust, but i know that the dragon fire racing exhaust will not. i would think that the muzzy pipes would pass i don't think they are as load as the dragon fire racing exhaust. that dragon fire racing pipe is load as hell. as for the cops cooling there heals during dunefest i don't know? i have always avoided the big crowds of people, but this year i will be there.
oregon law states: 93 db,
hunterworks stated the muzzy exhaust was 92 db's at 6000 rpm's and under a load was 104 db. so if you get checked don't put the rex under a load and you should be fine.
