I heard they haven't been checking sound, but it was more than 94 when I went, it was like max of 98.
As for the pipe passing, I am going to say it wont pass.
And it is random sound checks, but if you come to the gate and it is super loud, they usually check you.
When I talked to the locals with drag banshees, they put them in the back of a truck and the quads don't have flags on them, just sparkies.
