Exhaust is too loud

At 50' (SCCA autox rules) my car with FI CBE and LTH was ~93-94 dB.

Could just be settings on the sound meters. Early in the day we had stock 911's exceeding 100 db because the meter was set to "fast" response. Once it was changed to slow response everyone was easily under the 100 db max. Also the meter was measuring from the driver's side of the car not behind it.
