Hello fellow 991 crew! Am thinking of taking new GTS on track at Bedford this weekend. Noise limit is 101bB. Anyone know if the GTS passes this? I know GT3s struggle to stay under the dB limit, with drivers forced to short-shift. How does the GTS fare?
Out of curiosity, why are there limits, nearby residential areas?
that's it ... and in the case of Laguna Seca, the track was there before the houses, then homeowners complained about the noise - and voila noise
limits in the low 90's ...
I just played with a phone sound meter - doesn't look like the mic is sensitive
enough to measure an exhaust

Sound readings are influenced by atmospheric conditions and for on track readings, location. Obviously if the location is where your car is close to redline, higher numbers. And Laguna has some of the most restricted noise levels in the US (Lime Rock too) except on the few pro weekends. Cars that are normally unmuffled need them at LS.
At Roebling Road, we have the same problem. Only this is the church next to the track. We got around it by cutting the top and bottom out of a Pepsi can, a single cut down the side, affix to the exhaust tip with wire, and diverting the exhaust towards the infield.
