2013 Boss db levels?

I am set to run at Laguna Seca on a 103db day and I'm wondering if I should purchase some plates with 3/4" or 1/2" holes or if I can just run without any plates since I don't have any? The exhaust is stock, just with the sides open.
 
You'll be ok without the plates for a 103 db day. If running a 90 db day run the 1/2". Thanks for your order. You'll have them Sat or Mon as I'm in NorCal.

Great! I'm going to put the 7/8" in just to see how it sounds, and if I like it, I'll just keep them in full time. (Until I need to put the 1/2" in for 90 db days of course!)
