So then a stock car would pass, still probably not a modified one. |
Yea most likely. I was looking at the chart you linked great information btw. I was looking at the parameters of how it's being measured and they're different from ca state ref. State ref measures 20 inches away from the exhaust at a 45 degree angle which could have a big difference on the decibel level being read.
