Existing law requires the Commissioner of the California Highway Patrol to adopt regulations providing that exhaust systems comply with statutory noise restrictions if they are installed on motor vehicles, other than motorcycles and new motor vehicles, with a gross vehicular weight of less than 6,000 pounds and emit no more than 95 dbA.
Hmmmm, I don't see 86 dbA anywhere on that bill. Maybe you have a special version the rest of us don't?

Read further down. In Section 27150.2 (as amended), you'll see:
... no more than 95 dbA when tested in accordance with Society of Automotive Engineers Standard J1169 May 1998"
That's the "20 inches" I was talking about. SB 1420 doesn't nullify the "50 feet from the centerline" limits I quoted from Sections 27200 thru 27207 of the California Vehicle Code - those still stand.
If you (and Quietamerican for that matter) had a better understanding of the law, you'd both realize SB1420 isn't giving in to pro-noise pressure groups - it strengthens current law by providing specifications for noise testing at California inspection stations. For too long, California has endured a situation where, as CHP 98-100 so aptly states, "Accurately determining compliance with Sections 27201-27206 VC for enforcement purposes is generally impractical." SB1420 addresses that problem.
And, by the way, 95dbA at 20 inches equates to approximately 80 dbA at 50 feet. So there!
