how low will you go?

Local zoning regs. As part of the original deal, there's only X number of open-muffler competition days available. I think it started out as open, then went to 103dB later in its history.

This is one reason why 103dB competition days are so expensive at LRP: lack of supply.

Laguna Seca has the same issue (except 92 db). The unrestricted days are limited and most of the club days run at 92 db. Might be some useful information in learning how SFR racers cope with those restrictions.

Our recent experiences with noise in AZ could also be instructive for those devising ways to deal with potential noise issues (mostly as a "don't do this" sort of approach). When the county planners included a requirement for the track to monitor noise as a condition of continued use, they mandated a system that would measure average noise over a 2 minute period. The limits were to be 78db at the property line at the closest point to the track. Turned out to not be an issue when the county supervisors decided to rescind all use permits instead.

Now the track owner has reapplied for a use permit. The track's newest permit application calls for weekday operating hours of 9 a.m. to 5 p.m. and weekend and holiday hours of 10 a.m. to 6 p.m. It also would require vehicles to be equipped with mufflers and would restrict noise levels to 100 decibels, measured from a single monitoring station 50 feet from the track's edge. I would doubt that the county would approve those limits, based on past comments from the supervisors.
