In Grassroots Motorsports there was an advertisement for Vibrant Performance. I contacted the company referencing the CT dB standards and asking about a muffler specifically intended for Cobras. Included was the following comment . First time that I had seen a reference to an SAE standard on dB for exhaust noise.
"So you know, the Connecticut sound test you have referenced has been largely discredited by SAE (Society of Automotive Engineers) as being ineffective. In 1998 they released a new standard (known as J1169-1998) for exhaust noise testing that is the standard used by California and some other states. The new standard allows for a stationary db level of 95, at a distance of 1.5 meters from the tailpipe. This standard has proven to be very fair to manufacturers and enthusiasts alike. "
Anyone from CA familiar with the standard mentioned above ?
