Got popped for exhaust-CHP
 

CHP pulled me over on the highway, going about 80 in a 65. Got a speeding ticket but he also cited me for aftermarket exhaust. He also inspected my engine bay (lol). Was like "sooo just a blowoff valve?" Engine is completely stock, dude didn't really know what he was talking about and tried to argue my intake was tampered with due to a (factory) clamp not looking stock.

ONLY mod is Corsa catback (pretty quiet as far as aftermarket exhausts go). Stock headers, stock tune, just corsa and coilovers (thankfully he didn't say anything about my ride height ~1" lower than stock).

Anyways, i know this is not a fix it ticket anymore since Jan 2019. Exhaust has to be below 95 db when the engine is revved at 75% full throttle. I will go get it certified at the test center but has anyone had any experience with this relatively new CA law? IF it is above 95 decibels do you have to tow the car home or some **** ? Not sure how loud the corsa exhausts get but i dont think its 95 db.

Im assuming in the future, carry the cert in the car and show it to CHP if they give me shit for it.

Fine is like $200ish, but if you have whistle tips (LMAO welcome to 2003, california) its like $1000. Im more worried about what happens at the smog center if i do not pass the audio inspection.

Which area of CA are you located?
put back stock before you go?

Im from East Bay but this happened in North Bay on the 101. I dont have stock exhaust anymore.

Well, sucks to be you.
Only thing I can say is do you have money for lawyer? If not maybe cheaper to buy an oem muffler.

Or roll the dice and see how loud it is. If it's just a cat back and everything else is stock you may squeak on by.

According to Bureau of Automotive Repair, its not like they impound your car or anything. Just can't get cert'd and have to eat the fine.

I think i'll probably give it a shot.

Be careful out there guys especially if you've a modded vehicle! I was an idiot, i know that area well (in between Cotati and Petaluma) and it can be quite a speed trap.

This state is a joke.

California needs to train CHP officers how to fill potholes and suspend any fines until there are some safe roads to drive.

Maybe they need to fine us to fix the road, obvious tax money is not enough XD

I constantly visit Rohnert Park. Thanks, I’ll keep taking Lakeville Hwy. and the back roads. Stay safe everyone.

Wow, that’s unfortunate to hear. I remember when I got pulled over and the CHP officer was inspecting my engine bay, he saw my K&N sticker I have and almost tried telling me my K&N air filter was illegal. They really do have no clue what to look for, because you could clearly see my headers that say “JDL” on them but obviously he’s more interested in my air filter��

I'm fairly certain the Corsa is below 95DB. I run one as well and researched prior to buying. I've never actually tested it my self but I read it was around 87DB(don't quote me on this)

What was the exact CVC they cited the exhaust under?

I have a Corsa exhaust as well. I haven't measured the output myself but I read someone ran at Laguna Seca with a Corsa catback and stock everything else and was fine on a 91 dB day. Just as a comparison, my buddy's straight piped Evora got flagged when we were at Laguna Seca and I believe he was at ~94 dB at full throttle, and that thing was LOUD. I'm not sure how the noise check location at Laguna Seca compares with the audio test for California regulations, though.

I'm very positive you're well under 95 dB and will be fine.

1. You can drive the car. Its not a fix it, BUT if it were you can only drive it to the shop and home.

2. Test it yourself first, if you have to ask yourself the question, maybe swap it out. Not worth the risk.

I recently got state reffed so I had to deal with something similar.

What did you get a ticket for, exhaust as well?
