Sound test for AB 1824 exhaust law in CA
Got my car tested today to see where it stands with California’s new exhaust law AB 1824. Tested at idle, 2500rpm & 5200 rpm. Car passed on idle, but failed the 2500 & 5200rpm test.
The car should not exceed 95dB in order to pass.
We scored a 108dB stock headers with secondary cat delete and resonator delete.
Any guess on what it would be when I install my lth’s?

I have mbh headers full 🐱🤫 with xpipe which should quiet it down and my shop did a dB reading and it was pegged passed their dB measurement device of 135. Honestly could be the loudest street car with a muffler. The akra mufflers tremendously quiet the car down if you need to pass. With secondary delete. You’ll need to put the res back on. You’ll never pass with longtubes.

What a crock! So every Biker in Cali running a Harley is going to get pulled and fined $1,000? Good luck with that.

that’s not entirely true. The suggested base fine is $25 with a total fee of $193

That's what it used to be, along with fix it ticket, but now it's $1000 pretty sure...
Instagram has been going crazy about it. You could get cutouts to close by the cops but still sucks.
