991 Sports Exhaust (PSE) vs 105dB

[DKC]

Did a quick search but couldn't find the answer. I have a 991 C4S with PSE. Just booked my first track day which has a noise limit of 105dB.

I know the PSE in "quiet" mode should pass with no issues. However due to a failed swictchover valve solenoid (diagnosed by OPC) it is now stuck in "loud" mode.

Does anyone know whether the PSE in loud mode will pass 105dB? I need to decide if I have to fix the exhaust before my track day which is coming up.

Thanks!

Yes, it will pass a 105db test. The 991 PSE is <100db.
