yeah you would have to use a end cap with a 1/2 inch diameter hole in it to be under 96db
We tested the fmf with quiet core again at the dyno day . The quad at idle with your hand over the exhaust end cap so it doesnt make noise is at 91/92 db. When tested at test speed it again blew 98 . Mydreamrides huge R1 muffler blew identical numbers . I dont think a stock muffler would be any quieter. The engines make most of the noise. Get out the silicone and goop the covers or get the european side panel kits .
