Sonoma Raceway Noise Limit

danegrey

well wish I was allow 103db. It all depends, at Atlanta Motorsport Park limited to 98db, I have z1 headers / z1 test pipes resonated / FI exhaust with 18' mufflers resonated. Never got flagged. (Note this is at 50 feet from track)

So it might come down are the BerK HFC and Invidia cat-bat at all resonated. I had my built that way, because I new sound limits are in affect.

Just my 2 cents on what I have done. Another thought, its a bit cheaper, does Sonoma do any SCCA Track nights, the reason I ask, its 130-155 to run, might be a cheap experiment to see if you get bounced....
