My exhaust is not stock - I have a 4-1 header and a 3" Lindsey Racing exhaust. It has a high-flow cat and magnaflow muffler, so it's loud, but I don't think that it's as loud as, say, a 911 with straight pipes.

I'm sorry if I missed this somewhere, but does anybody know at what distance the 86 dB limit is enforced at? 50 ft? 75?

It's 88db (now) and I would say it's about 50' as they stand near the edge of the track..

I've seen stock 996 turbo's Black flagged so all you can do is hope it isn't cloudy that day..

Thanks, I'm definitely hoping for good weather, but I'd rather not have to worry about this at all - this being the first event of the season, I will have enough other things on the car to worry about!

I did a little more research on search/google and found this thread, which said that a 944 turbo with a similar exhaust (but no cat or muffler) read 93 dB at 10 ft.

Plugged into this calculator, that is 79 dB at 50 ft. While I know the turbo will quiet the exhaust, I imagine that its effect would be comparable to that of a cat and muffler. Not to mention the 9dB cushion between 79 dB and 88 - even if its a little louder, my car can't be almost 2x louder than a 951 with straight pipes, right?

Stock 997 GT3s have a hard enough time passing 92db at laguna in "sport" mode. And by hard enough, I mean they DON'T pass.

We could have a moment of silence before the day starts. They might average the noise level

88dB is just incredibly & unrealistically low for a serious race track.

I think they are going to make it a 100% private club for electric go karts...

VR... nobody said they are serious about racing anymore!

Stock vehicles in sport mode with a strong driver ? We are only weeks away. One and your done policy?
It may get worse as the season progresses as everyone gets up to speed with more seat time and grip = louder

Ah, Kevin, so that's why I never see you until later in the season!

I've been going to LRP for years, and although I've had great successes there it is my least favorite track. It's just too short. Now Mike, if your buddy has a better track right in the area, bring it on! Even if LRP goes the Drivers Club route, I won't miss it much.

Let's all start racing Chevy Volts!!!

I was planning on signing up for a day, but I think I'm stuck with my GMG exhaust being much too loud.

Don, are you coming up for the race?

How about a group buy on Tesla's!

OK, so they are going to be strict about the 88db at DE's. How about the "unmuffled" 10 days. 105db can be a problem for many race cars. Doesn't unmuffled mean unmuffled?
