At Laguna it’s measured 50 feet away, track right. It’s a little pass T5 on a uphill straight, so you’ll be full throttle in 3rd gear. Pretty much none of the aftermarket exhaust pass sound, (other then the 8") Stage II or the Arqray twin mufflers are the closest, about 5dbA off. The Arqray single tip at full song was a good 14dbA off. Not only did he have to short shift and lift, he practically had to coast by the sound station to stay on track.
They will allow you to do a sound check- 3 laps, first a warm up a hot lap in the clear then a cool down lap. That don’t count as a strike against you.
