My street muffler which is pretty quiet at idle will not pass the 92dB limit on the track. Feedback from the racer guys has it at ~94dB. One of my projects, the Quiet Riot, has a 90dB goal that is proving difficult to meet without impacting performance and looking like you've got a suitcase strapped to your engine. You can only imagine what a zork puts out ...
