YZF Shorty silencer w/PMB pass sound check at Enduro?

[Bandit9]

Anyone had their YZF PMB set up sound checked? I'm worried it won't pass 96 with fresh packing.

Not to steal the thread but is it measured at idle or wide open? We have a 92 decibel law here now and I'm wondering if my stock exhaust with restrictor removed is under it as well

They hold it steady at like 4k rpm, then measure.

I don't believe it will be at 92, more like 95-96 with both baffles removed. That is just a guess based on my experience, my 06 passed Enduro sound test with that same setup.
