Pfffft, doubt it is
I think it is aimed at straight piped Hondas, external wastegates and Rotary power cars that shake the surrounding areas, any decent muffled exhaust should be fine hopefully. Most GTR's, EVO's and WRX's can have loud exhausts but the sound does not carry as far as buzz boxes.
I also concur with Alex about the 3rd runway, our business (FYI; I work for Perth Airport) has slowed steadily over the last few years and while we still struggle at peak times with the current runway that is only for 2hrs morning and night really. The rest of the day it cruises along fine. Plus most airlines are investing in larger more efficient aircraft so that may lead to less flights.
