David Anderson, member of GGLC runs his Elan Sprint frequently at Laguna. As posted earlier, a stock airbox over the Webers or Strombergs with hose to the air filter in the nose, a turnout for the tailpipe to drivers left will go a long way to meeting the requirements. 90dBA is pretty close to stock exhaust level. Overcast days, especially fog will affect sound readings too. The overall noise level of your entire car determines whether you are black flagged for noise, not just exhaust.
The sound shack and microphone at Laguna is on drivers' right, between Turns 5 and 6 before the bridge.
Please PM me if you would like Dave's contact info.
