Motorcycles have a higher noise allowance. Blame the legislators.

Best solution is to have a compliant exhaust. If your employer subjected you to 95dBA noise they'd be required to furnish hearing protection and do an annual medical hearing test for everyone employed there.

Quick (plagerized) note:
OSHA sets legal limits on noise exposure in the workplace. ... Here's an example: OSHA allows 8 hours of exposure to 90 dBA but only 2 hours of exposure to 100 dBA sound levels. NIOSH would recommend limiting the 8 hour exposure to less than 85 dBA. At 100 dBA, NIOSH recommends less than 15 minutes of exposure per day.
Look at the little video link I posted a day or two ago. The Invidia Q300 they use for the example is much louder than any of of these. They eventually got it compliant. In the cockpit will be less just to distance, but I can tell ya earplugs are a literal requirement driving a car with that exhaust as it comes out of the box. .

When those first came out, everyone was raving "its the QUIET 70! Sounds awesome but close to stock!" I bought one and put it up for sale on this board an hour after installing it. Bloody awful thing gave me a splitting headache on the first test drive.

When some push the limits or just flat blow through them then the law will get involved.

Except I'm pretty sure it doesn't cover motorcycles or vehicles over 6,000 lbs.

The Invidia Q300 lasted 3 weeks on my car but only because it took 2 weeks to get the Tanabe Medalion Touring to Ohio from the vendor in California. A buddy helped me install the Q300 on my car and liked the sound. Except he didn't after about the same time. He sold his as well. Every time I mention how horrible the Q300 is I get snide comments from one guy. Maybe he likes his or is deaf? My routine advice is to hear any potential exhaust for a good length of time inside an identical car before deciding. In addition I adamantly recommend NOT buying the Q300.

I think this is the case. The noise limit in California has always been 95db, this law only increased the penalty.

Your ability to complain about the Q300 in every thread is incredible.

California: Change your gender, not your exhaust.

If best case: would it be beneficial to get pulled over on a highway since there are ALOT of road noise?

Worse case: in a quiet neighborhood.
Can you kindly link a source?

Just look up the law, the original law didn't really change. It's just that instead of a fix it ticket, you'll get fined right away.

As far as the test goes, you've been able to test your exhaust for a while now, but you usually had to have a citation to be able to go to ref station to have your exhaust tested and certified to be below the 95DB mark.It was SEMA who helped get the law in place that allowed the test to better help enthusiast fight tickets. There should be plenty of articles to look it up on this subject.

There have been some talk about how the test was done, and from what I remember what dea7hrow mentioned was similar to how they tested.
