Sound dB limit
Is there anyone out there that is running headers and high flow cats that stayed under the DB limit? I am running headers with high flow cats that connect into the stock muffler. A little concerned about track sound dB limit.

I ran last year with that same setup with no problems. You should be fine.

Agree with Bad Dab - chambered stock mufflers should be fine. I blew the sound limit there in 2017 with cam, headers, hi-flo cats and Borla ATAK mufflers (104.7 dB). Came back last year with Borla S-Type mufflers and passed.

Let’s try again for a two day NCM at the next CamaroFest. How close were we last year to having enough cars to do the second day?

Follow up, what are the minimum required sign ups to do the HALF course?
Might it be possible to do the half course on the wednesday to support a smaller number of registrations, then the full course the next day when the cavalry comes in?

I couldn't make it this year but I would pay for 2 days at NCM like the first year at BG. This has become an annual vacation destination for me and we're also at an iconic track to boot so we need to offer this early on during the initial signup period.
