Anyone measured their sound levels with the standard exhaust? Wondering if the high Revs will place us at risk for running Laguna Seca etc.

There's no way the new 991 GT3 will pass the new 90dB limits.

Known STOCK cars that wont pass 92dB:
997 GT3
997 TT
987.1
981 with sport exhaust turned OFF

Laguna is a travesty.

I didn't think so, was hoping for a miracle, it should be less than 105db? Right?

orthojoe

I think that is a safe assumption.

MRLS 90dB now? A honda accord makes more noise than that

paver

it will be a lot less than 105

Would be nice to know the decibel levels both with and without the sport exhaust engaged...

Here it is from the Certificate of Compliance (PAG) that was shipped with my car. This is the official Porsche doc for the car (assume its accurate). 96db at 4000rpm.

96dB at 4000rpm only? Man, it's got to be over 100dB once you're screaming to redline. Must sound awesome. Too bad the car will be instantly black flagged a laguna. All because of a handful of people determined to be scumbags....

I wonder how that got it approved for street use in CA where the max allowable is 95db?

Maybe that 96 dB figure is when measured very close to the exhaust, whereas racetracks measure at a distance?

That's true for Laguna where the shack is pretty far off the track. My ol Subaru STI was definitely a 98+db exhaust and I didn't get flagged. However CA test requirement is at the exhaust.
