Default GMG center delete less than 103 dB?

Quick question to those who frequent Laguna. Will a .2 GT3 RS with a GMG center delete exhaust pass sound at Laguna with a 103 dB limit?

Nope.
Need silencer or just lift if you know where the measurement station is.

Bummer. Might slip the OEM back on just for the event. OEM should work, right?

Not GMG, but my .2 RS with Sharkwerks center bypass got hit for 105 and 104 in Laguna Seca. I thought I was safe on a 103 dB day, which is a rare event.

Thanks for that info. I'm running a 103 day there next week and thought I might try a session with the Track Nanny turned off but if that is the case I won't bother. It will be nice to leave the regular tips on and not lift though.

It will be tight, a lot depends on the cloud cover and weather but leave sport mode off for sure......and lifting at the right time only costs about 1.5 seconds at Laguna....
Do know that even stock is pretty loud there due to the intake as well.
