For the record, a stock WRX is 87dB and an STI is 92dB. Those are measured from a complete stop within 3' so the final reading will vary at 35mph from 50'. I'm not sure how much though, but those numbers are considerably higher than the statute. I got EL headers on my car which helped quiet my car down but then added a TurboXS axle back which brought it back up a little. I'm probably at or just above stock but I never get harassed up here in NY. We'll see when I move to FL.
