It would have been much faster but I had a helluva time getting my hands in the tight spaces to hook up the electronics; my first time working on a Porsche! Very doable though. My 991.1 GT3 has a GMG center muffler delete and it is LOUD. I used the Track Nanny for my first two sessions at Thunderhill. Everybody I talked to said they had never heard of anyone getting flagged for sound at Thunderhill so I turned it off for session three. Flagged for sound after one lap at 105db. Turned it back on for my last two sessions and no issues whatsoever.You also have full control of the valves with the controller; you can leave the valves open all the time, keep the stock setup, or switch to the GPS track setup. I highly recommend this for anyone with modified exhaust, and it’s a must-have even with stock exhaust at Laguna. Tom was also super responsive and even expedited the shipping to get it to me in time for the track day.

Thanks again Tom!

Howdy and welcome to Carpokes. I'd have to look so see if I've ever done one for that track, but it's not ringing a bell. I have, however, pre-programmed Track Nannies to work all over the globe (e.g., Australia, Germany, multiple states, etc.) so as long the sound meter is in a fixed location, it should work. What I don't know is if your car will be quiet enough, even with the Track Nanny engaged. For reference, a stock 981 GT4 will stay under the 92db limit at Laguna Seca with the Track Nanny. Looks like Atlanta Motorsport Park has a limit of 98db, which is promising, though I'd caution that db limits are not necessarily comparable since there are so many other variables at play.

Is your exhaust modified?

I’m currently running catless soul headers with PSE. I’m pretty sure with a track nanny setup I should be okay because last time I was there a 991.2 GT3RS with a modified exhaust never got flagged. The only problem is I’m not even sure where the mics are. They say they measure 50 feet from the track edge.
