101db static is usually done by holding the noise meter 0.5 metres from the exhaust at an angle of 45 degrees to the tailpipe and then holding 3/4 of your maximum revs. The driveby I doubt you are going to be able to replicate - depends on distance from the meter, throttle opening, ambient conditions, which side your exhaust pipe is on, whether your induction is louder than your exhaust, etc. If you are borderline on the static test then there's probably a good chance of failing the drive by.
