What the db are of an FMF Ti4 exhaust system with a quiet core insert and spark arrestor? Thinking of heading to Hollister this weekend and I know they sound check the bikes.

if it's a "QUIET", and united forest service approved, you should definetly be good to go.. specially if it is quiet. a lot of local off-road races require 96DB.. not sure if it is the same for cally though
