White Bros R4 exhaust decibel rating

[Screamin440]

Before you guys say anything, I've already done a search and I couldn't find anything related to what I'm looking for.

Does anyone know what the decibel rating is on an R4 with no quiet core insert and no spark arrestor? I'm wanting to hit a few local GNCC races this year and I'm wondering if I'll be able to fly under the noise level testing without buying the add-on pieces.

BTW, I have a Powerbomb header as well.

I have a pretty good feeling that your going to be too loud. I dont know the exact decibal rating, but it is loud, which is one of the reasons they discontinued it.
